Struct mesh_protobuf::buffer::Buf
source · pub struct Buf<'a> { /* private fields */ }
Expand description
An accessor for writing to a partially-initialized byte buffer.
Implementations§
source§impl<'a> Buf<'a>
impl<'a> Buf<'a>
sourcepub fn push(&mut self, b: u8)
pub fn push(&mut self, b: u8)
Extends the initialized portion of the buffer with b
. Panics if it
doesn’t fit.
sourcepub fn append(&mut self, buf: &[u8])
pub fn append(&mut self, buf: &[u8])
Extends the initialized portion of the buffer with buf
. Panics if the
data does not fit.
sourcepub fn fill(&mut self, val: u8, len: usize)
pub fn fill(&mut self, val: u8, len: usize)
Extends the initialized portion of the buffer with len
bytes equal to
val
. Panics if the data does not fit.
sourcepub fn write_split<R>(
&mut self,
split_at: usize,
f: impl FnOnce(Buf<'_>, Buf<'_>) -> R,
) -> R
pub fn write_split<R>( &mut self, split_at: usize, f: impl FnOnce(Buf<'_>, Buf<'_>) -> R, ) -> R
Splits this buffer into two at split_at
and calls f
to fill out each
part.
If the left buffer is not filled in full but the right buffer is partially initialized, then the remainder of the left buffer will be zero-initialized.
