Trait git_repository::prelude::Header

pub trait Header {
    type Error: 'static + Error;

    fn try_header(
        &self,
        id: impl AsRef<oid>
    ) -> Result<Option<Header>, Self::Error>;
}

A way to obtain object properties without fully decoding it.

Required Associated Types

type Error: 'static + Error

Required Methods

fn try_header(&self, id: impl AsRef<oid>) -> Result<Option<Header>, Self::Error>
