Struct zstd_safe::OutBuffer

source · [−]

pub struct OutBuffer<'a, C: WriteBuf + ?Sized> {
    pub dst: &'a mut C,
    /* private fields */
}

Expand description

Wrapper around an output buffer.

C is usually either [u8] or Vec<u8>.

Bytes will be written starting at dst[pos].

pos will be updated after writing.

Invariant

pos <= dst.capacity()

Fields

dst: &'a mut C

Implementations

source

impl<'a, C: WriteBuf + ?Sized> OutBuffer<'a, C>

source

pub fn around(dst: &'a mut C) -> Self

Returns a new OutBuffer around the given slice.

Starts with pos = 0.

source

pub fn around_pos(dst: &'a mut C, pos: usize) -> Self

Returns a new OutBuffer around the given slice, starting at the given position.

Panics

If pos >= dst.capacity().

source

pub fn pos(&self) -> usize

Returns the current cursor position.

source

pub unsafe fn set_pos(&mut self, pos: usize)

Sets the new cursor position.

Panics

If pos > self.dst.capacity().

Safety

Data up to pos must have actually been written to.

'b: 'a,

Returns the part of this buffer that was written to.
