Enum rustix::net::SendAncillaryMessage

source ·
#[non_exhaustive]
pub enum SendAncillaryMessage<'slice, 'fd> { ScmRights(&'slice [BorrowedFd<'fd>]), ScmCredentials(UCred), }
Expand description

Ancillary message for sendmsg, sendmsg_v4, sendmsg_v6, sendmsg_unix, and sendmsg_any.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

ScmRights(&'slice [BorrowedFd<'fd>])

Send file descriptors.

§

ScmCredentials(UCred)

Send process credentials.

Implementations§

source§

impl SendAncillaryMessage<'_, '_>

source

pub const fn size(&self) -> usize

Get the maximum size of an ancillary message.

This can be helpful in determining the size of the buffer you allocate.
