Struct FetchClientConfig 

pub struct FetchClientConfig {
    pub tls_built_in_webpki_certs: bool,
    pub tls_built_in_native_certs: bool,
}

Represents the configuration needed to construct a [reqwest::Client].

This is used to cache clients keyed by their configuration, so the configuration should contain as few fields as possible and change infrequently.

This is needed because [reqwest::ClientBuilder] does not implement the required traits. This factory cannot be a closure because closures do not implement Eq or Hash.

Fields

tls_built_in_webpki_certs: bool

Whether to load embedded webpki root certs with rustls. Default is true.

Ignored for:

• Windows on ARM, which uses native-tls instead of rustls-tls.
• Ignored for WASM targets, which use the runtime’s TLS implementation.

tls_built_in_native_certs: bool

Whether to load native root certs using the rustls-native-certs crate. This may make reqwest client initialization slower, so it’s not used by default.

Ignored for:

• Windows on ARM, which uses native-tls instead of rustls-tls.
• Ignored for WASM targets, which use the runtime’s TLS implementation.

Implementations

impl FetchClientConfig

pub fn cell(self) -> Vc<Self>

Places a value in a cell of the current task.

Cell is selected based on the value type and call order of cell.

pub fn resolved_cell(self) -> ResolvedVc<Self>

Places a value in a cell of the current task. Returns a [ResolvedVc][turbo_tasks::ResolvedVc].

Cell is selected based on the value type and call order of cell.

impl FetchClientConfig

pub fn try_get_cached_reqwest_client( self: ReadRef<FetchClientConfig>, ) -> Result<Client>

Returns a cached instance of reqwest::Client it exists, otherwise constructs a new one.

The cache is bound in size to prevent accidental blowups or leaks. However, in practice, very few clients should be created, likely only when the bundler configuration changes.

Client construction is largely deterministic, aside from changes to system TLS configuration.

The reqwest client fails to construct if the TLS backend cannot be initialized, or the resolver cannot load the system configuration. These failures should be treated as cached for some amount of time, but ultimately transient (e.g. using [turbo_tasks::mark_session_dependent]).

impl FetchClientConfig

pub fn fetch( self: Vc<Self>, url: RcStr, user_agent: Option<RcStr>, ) -> Vc<FetchResult>

Trait Implementations

impl Default for FetchClientConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FetchClientConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FetchClientConfig> for Vc<FetchClientConfig>

fn from(value: FetchClientConfig) -> Self

Converts to this type from the input type.

impl Hash for FetchClientConfig

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FetchClientConfig

fn eq(&self, other: &FetchClientConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ValueDebug for FetchClientConfig

fn dbg(self: Vc<Self>) -> Vc<ValueDebugString>

fn dbg_depth(self: Vc<Self>, depth: usize) -> Vc<ValueDebugString>

Like dbg, but with a depth limit.

impl ValueDebugFormat for FetchClientConfig

impl VcValueType for FetchClientConfig

type Read = VcDefaultRead<FetchClientConfig>

How to read the value.

type CellMode = VcCellSharedMode<FetchClientConfig>
