Trait partial_io::ReadBufExt

pub trait ReadBufExt {
    fn with_limited<F, T>(&mut self, limit: usize, callback: F) -> T
    where
        F: FnOnce(&mut ReadBuf<'_>) -> T;
}

Extensions to tokio’s ReadBuf.

Requires the tokio1 feature to be enabled.

Required Methods

fn with_limited<F, T>(&mut self, limit: usize, callback: F) -> T where
    F: FnOnce(&mut ReadBuf<'_>) -> T, 

Convert this ReadBuf into a limited one backed by the same storage, then call the callback with this limited instance..

Any changes to the ReadBuf made by the callback are reflected in the original ReadBuf.
