[−][src]Trait http_api_problem::HttpTryFrom
Private trait for the http crate to have generic methods with fallible
conversions.
This trait is similar to the TryFrom trait proposed in the standard
library, except this is specialized for the http crate and isn't intended
for general consumption.
This trait cannot be implemented types outside of the http crate, and is
only intended for use as a generic bound on methods in the http crate.
