Struct error_code::StrBuf

pub struct StrBuf<T: Sized> { /* fields omitted */ }

Stack based string.

Implementations

impl<S: Sized> StrBuf<S>

pub const fn new() -> Self

Creates new instance

pub const fn as_ptr(&self) -> *const u8

Returns pointer to the beginning of underlying buffer

pub const fn remaining(&self) -> usize

Returns number of bytes left (not written yet)

pub fn as_slice(&self) -> &[u8]

Returns slice to already written data.

pub fn as_mut_slice(&mut self) -> &mut [u8]

Returns mutable slice to already written data.

pub fn truncate(&mut self, cursor: u8)

Shortens the buffer.

Does nothing if new cursor is after current position.

pub const fn capacity() -> usize

Returns buffer overall capacity.

pub const fn len(&self) -> usize

Returns number of bytes written.

pub fn push_str(&mut self, text: &str)

Appends given string, truncating on overflow

pub fn as_str(&self) -> &str

Access str from underlying storage

Returns empty if nothing has been written into buffer yet.
