Enum ValueDebugFormatString 

pub enum ValueDebugFormatString<'a> {
    Sync(String),
    Async(BoxFuture<'a, Result<String>>),
}

Output of ValueDebugFormat::value_debug_format.

Variants

Sync(String)

For the T: Debug fallback implementation, we can output a string directly as the result of format!("{:?}", t).

Async(BoxFuture<'a, Result<String>>)

For the Vc types and Vc-containing types implementations, we need to resolve types asynchronously before we can format them, hence the need for a future.

Implementations

impl ValueDebugFormatString<'_>

pub async fn try_to_string(self) -> Result<String>

Convert the ValueDebugFormatString into a String.

This can fail when resolving Vc types.
