LengthSetter

Struct LengthSetter 

Source 
pub struct LengthSetter<'a> { /* private fields */ }
Expand description

A destructured component of WordVec to support setting length.

See WordVec::as_uninit_slice_with_length_setter().

Implementations§

Source§

impl LengthSetter<'_>

Source

pub unsafe fn set_len(&mut self, new_len: usize)

Sets the raw length of this vector.

§Safety
  • new_len must be less than or equal to the current capacity.
  • The first new_len items of the vector must be initialized.
Source

pub unsafe fn inc_len(&mut self)

Increments the raw length of this vector by 1.

§Safety

This has the same safety invariants as set_len, with new_len being the current raw length plus one.
