Enum rustc_target::spec::StackProbeType

pub enum StackProbeType {
    None,
    Inline,
    Call,
    InlineOrCall {
        min_llvm_version_for_inline: (u32, u32, u32),
    },
}

Variants

None

Don’t emit any stack probes.

Inline

It is harmless to use this option even on targets that do not have backend support for stack probes as the failure mode is the same as if no stack-probe option was specified in the first place.

Call

Call __rust_probestack whenever stack needs to be probed.

InlineOrCall

Use inline option for LLVM versions later than specified in min_llvm_version_for_inline and call __rust_probestack otherwise.

Fields

min_llvm_version_for_inline: (u32, u32, u32)

Implementations

impl StackProbeType

fn from_json(json: &Json) -> Result<Self, String>

Trait Implementations

impl Clone for StackProbeType

fn clone(&self) -> StackProbeType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StackProbeType

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

Formats the value using the given formatter.

impl PartialEq for StackProbeType

fn eq(&self, other: &StackProbeType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToJson for StackProbeType

fn to_json(&self) -> Json

impl Eq for StackProbeType

impl StructuralPartialEq for StackProbeType

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
