Struct runa_wayland_protocols::wayland::wl_shm_pool::v1::requests::Resize

pub struct Resize {
    pub size: i32,
}

change the size of the pool mapping

This request will cause the server to remap the backing memory for the pool from the file descriptor passed when the pool was created, but using the new size. This request can only be used to make the pool bigger.

This request only changes the amount of bytes that are mmapped by the server and does not touch the file corresponding to the file descriptor passed at creation time. It is the client’s responsibility to ensure that the file is at least as big as the new pool size.

Trait Implementations

impl Clone for Resize

fn clone(&self) -> Resize

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Resize

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for Resize

fn deserialize(data: &'a [u8], fds: &'a [RawFd]) -> Result<Self, Error>

Deserialize from the given buffer. Returns deserialized message, and number of bytes and file descriptors consumed, respectively.

impl PartialEq<Resize> for Resize

fn eq(&self, other: &Resize) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Resize

fn serialize<Fds: Extend<OwnedFd>>(self, buf: &mut BytesMut, fds: &mut Fds)

Serialize into the buffered writer. This function returns no errors, failures in seializing are generally program errors, and triggers panicking.

fn len(&self) -> u16

How many bytes will this message serialize to. Including the 8 byte header.

fn nfds(&self) -> u8

How many file descriptors will this message serialize to.

impl Eq for Resize

impl StructuralEq for Resize

impl StructuralPartialEq for Resize
