}Expand description
Interface for byte vectors.
This train provides is used as an abstraction over different byte vector
implementations. It is implemented for static vectors (heapless::Vec<u8>)
and (if the alloc feature is used( for dynamic vectors (alloc::Vec<u8>).
Required Methods
sourcefn push(&mut self, b: u8) -> Result<(), OutOfMemory>
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.
sourcefn truncate(&mut self, len: usize)
fn truncate(&mut self, len: usize)
Shortens the vector, keeping the first len elements and dropping the rest.
sourcefn extend_from_slice(&mut self, other: &[u8]) -> Result<(), OutOfMemory>
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.
