Struct sunrise_kernel::utils::CursorRead

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

A minimal Cursor for writing, for use in libcore.

See https://doc.rust-lang.org/std/io/struct.Cursor.html

Fields

data: &'a [u8]

Data backing this cursor.

pos: Cell<usize>

Position of the cursor in the data.

Implementations

impl<'a> CursorRead<'a>

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

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 read_u8<BO>(&self) -> u8 where
    BO: ByteOrder, 

Reads an u8 in the given byteorder.

pub fn read_u16<BO>(&self) -> u16 where
    BO: ByteOrder, 

Reads an u16 in the given byteorder.

pub fn read_u32<BO>(&self) -> u32 where
    BO: ByteOrder, 

Reads an u32 in the given byteorder.

pub fn read_u64<BO>(&self) -> u64 where
    BO: ByteOrder, 

Reads an u64 in the given byteorder.

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

Reads v.len() bytes from the stream, and asserts that it is equal to v.

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

Skips bytelen bytes, returning a slice to them for inspection.

pub fn read_raw<T>(&self) -> T where
    T: Copy, 

Reads the given structure from the bytestream.
