Struct uefi_raw::table::boot::Tpl

#[repr(transparent)]
pub struct Tpl(pub usize);

Task priority level.

Although the UEFI specification repeatedly states that only the variants specified below should be used in application-provided input, as the other are reserved for internal firmware use, it might still happen that the firmware accidentally discloses one of these internal TPLs to us.

Since feeding an unexpected variant to a Rust enum is UB, this means that this C enum must be interfaced via the newtype pattern.

Tuple Fields

0: usize

Implementations

impl Tpl

pub const APPLICATION: Tpl = _

Normal task execution level.

pub const CALLBACK: Tpl = _

Async interrupt-style callbacks run at this TPL.

pub const NOTIFY: Tpl = _

Notifications are masked at this level.

This is used in critical sections of code.

pub const HIGH_LEVEL: Tpl = _

Highest priority level.

Even processor interrupts are disable at this level.

Trait Implementations

impl Clone for Tpl

fn clone(&self) -> Tpl

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tpl

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

Formats the value using the given formatter.

impl PartialEq for Tpl

fn eq(&self, other: &Tpl) -> 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.
