Struct uefi::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.

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.
