Trait x11rb_protocol::x11_utils::TryParseFd
source · [−]pub trait TryParseFd: Sized {
fn try_parse_fd<'a>(
value: &'a [u8],
fds: &mut Vec<RawFdContainer>
) -> Result<(Self, &'a [u8]), ParseError>;
}Expand description
A type implementing this trait can be parsed from some raw bytes and a list of fds.
Required Methods
fn try_parse_fd<'a>(
value: &'a [u8],
fds: &mut Vec<RawFdContainer>
) -> Result<(Self, &'a [u8]), ParseError>
fn try_parse_fd<'a>(
value: &'a [u8],
fds: &mut Vec<RawFdContainer>
) -> Result<(Self, &'a [u8]), ParseError>
Try to parse the given values into an instance of this type.
File descriptors are consumed by removing them from the beginning of the given fds Vec.
If a file descriptor is expected, but missing, a ParseError should be returned. If more file
descriptors are provided than expected, this is not an error and the remaining descriptors
should be left in the Vec.
If parsing is successful, an instance of the type and a slice for the remaining data should be returned. Otherwise, an error is returned.
