Function readFirstAssumeLength [src]

Reads first length bytes written to the ring buffer into dest; Asserts that length not greater than ring buffer or dest length Uses memcpy and so dest must not overlap ring buffer data.

Prototype

pub fn readFirstAssumeLength(self: *RingBuffer, dest: []u8, length: usize) void

Parameters

self: *RingBufferdest: []u8length: usize

Source

  pub fn readFirstAssumeLength(self: *RingBuffer, dest: []u8, length: usize) void {
    assert(length <= self.len() and length <= dest.len);
    const slice = self.sliceAt(self.read_index, length);
    slice.copyTo(dest);
    self.read_index = self.mask2(self.read_index + length);
}
