Trait ReadBufExt

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

Available on crate features tokio1 and futures03 only.

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
