Trait Buffer

pub trait Buffer:
    Default
    + Deref<Target = [u8]>
    + Sealed {
    // Required methods
    fn push(&mut self, b: u8) -> Result<(), OutOfMemory>;
    fn truncate(&mut self, len: usize);
    fn clear(&mut self);
    fn extend_from_slice(&mut self, other: &[u8]) -> Result<(), OutOfMemory>;
}

Interface for byte vectors.

This train provides is used as an abstraction over different byte vector implementations. It is implemented for static vectors (ArrayBuf) and (if the alloc feature is used) for dynamic vectors (alloc::Vec<u8>).

Required Methods

fn push(&mut self, b: u8) -> Result<(), OutOfMemory>

Appends a byte to the back of the vector.

Returns Err if the vector is full and could not be extended.

fn truncate(&mut self, len: usize)

Shortens the vector, keeping the first len elements and dropping the rest.

fn clear(&mut self)

Clears the vector, removing all values.

fn extend_from_slice(&mut self, other: &[u8]) -> Result<(), OutOfMemory>

Clones and appends all bytes in a slice to the vector.

Iterates over the slice other and appends each byte to this vector. The other vector is traversed in-order.

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.
