pub struct CursorWrite<'a> {
    data: &'a mut [u8],
    pos: usize,
}

Fields

data: &'a mut [u8]

Data backing this cursor.

pos: usize

Position of the cursor in the data.

Implementations

impl<'a> CursorWrite<'a>

pub fn new(data: &mut [u8]) -> CursorWrite

Creates a new cursor wrapping the provided underlying in-memory buffer.

pub fn pos(&self) -> usize

Returns the current position of this cursor.

pub fn skip_write(&mut self, bytelen: usize) -> &mut [u8]

Skip the given amount of bytes, returning a mutable slice to it.

pub fn write_u8<BO>(&mut self, v: u8) where
    BO: ByteOrder, 

Writes an u8 in the given byte ordering.

pub fn write_u16<BO>(&mut self, v: u16) where
    BO: ByteOrder, 

Writes a u16 in the given byte ordering.

pub fn write_u32<BO>(&mut self, v: u32) where
    BO: ByteOrder, 

Writes a u32 in the given byte ordering.

pub fn write_u64<BO>(&mut self, v: u64) where
    BO: ByteOrder, 

Writes a u64 in the given byte ordering.

pub fn write(&mut self, v: &[u8])

Writes the given byte slice entirely.

pub fn write_raw<T>(&mut self, v: T) where
    T: Copy, 

Writes the given structure.
