Implementations

impl CodegenFnAttrFlags[src]

pub const COLD: CodegenFnAttrFlags[src]

#[cold]: a hint to LLVM that this function, when called, is never on the hot path.

pub const ALLOCATOR: CodegenFnAttrFlags[src]

#[rustc_allocator]: a hint to LLVM that the pointer returned from this function is never null.

pub const UNWIND: CodegenFnAttrFlags[src]

#[unwind]: an indicator that this function may unwind despite what its ABI signature may otherwise imply.

pub const RUSTC_ALLOCATOR_NOUNWIND: CodegenFnAttrFlags[src]

#[rust_allocator_nounwind], an indicator that an imported FFI function will never unwind. Probably obsolete by recent changes with #[unwind], but hasn't been removed/migrated yet

pub const NAKED: CodegenFnAttrFlags[src]

#[naked]: an indicator to LLVM that no function prologue/epilogue should be generated.

pub const NO_MANGLE: CodegenFnAttrFlags[src]

#[no_mangle]: an indicator that the function's name should be the same as its symbol.

pub const RUSTC_STD_INTERNAL_SYMBOL: CodegenFnAttrFlags[src]

#[rustc_std_internal_symbol]: an indicator that this symbol is a "weird symbol" for the standard library in that it has slightly different linkage, visibility, and reachability rules.

pub const THREAD_LOCAL: CodegenFnAttrFlags[src]

#[thread_local]: indicates a static is actually a thread local piece of memory

pub const USED: CodegenFnAttrFlags[src]

#[used]: indicates that LLVM can't eliminate this function (but the linker can!).

pub const FFI_RETURNS_TWICE: CodegenFnAttrFlags[src]

#[ffi_returns_twice], indicates that an extern function can return multiple times

pub const TRACK_CALLER: CodegenFnAttrFlags[src]

#[track_caller]: allow access to the caller location

pub const FFI_PURE: CodegenFnAttrFlags[src]

#[ffi_pure]: applies clang's pure attribute to a foreign function declaration.

pub const FFI_CONST: CodegenFnAttrFlags[src]

#[ffi_const]: applies clang's const attribute to a foreign function declaration.

pub const CMSE_NONSECURE_ENTRY: CodegenFnAttrFlags[src]

#[cmse_nonsecure_entry]: with a TrustZone-M extension, declare a function as an entry function from Non-Secure code.

pub const fn empty() -> CodegenFnAttrFlags[src]

Returns an empty set of flags

pub const fn all() -> CodegenFnAttrFlags[src]

Returns the set containing all flags.

pub const fn bits(&self) -> u32[src]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<CodegenFnAttrFlags>[src]

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> CodegenFnAttrFlags[src]

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> CodegenFnAttrFlags[src]

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool[src]

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool[src]

Returns true if all flags are currently set.

pub const fn intersects(&self, other: CodegenFnAttrFlags) -> bool[src]

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: CodegenFnAttrFlags) -> bool[src]

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: CodegenFnAttrFlags)[src]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: CodegenFnAttrFlags)[src]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: CodegenFnAttrFlags)[src]

Toggles the specified flags in-place.

pub fn set(&mut self, other: CodegenFnAttrFlags, value: bool)[src]

Inserts or removes the specified flags depending on the passed value.
