Enum Eflags 

pub enum Eflags {
    None,
    R,
    W,
    RW,
}

Describes if an instruction uses EFLAGS, and whether it reads, writes, or reads/writes the EFLAGS register. In the future, we might want to model specific EFLAGS bits instead of the entire EFLAGS register. Some related discussion in this GitHub issue https://github.com/bytecodealliance/wasmtime/issues/10298

Implementations

impl Eflags

pub fn is_read(&self) -> bool

Returns whether this represents a read of any bit in the EFLAGS register.

pub fn is_write(&self) -> bool

Returns whether this represents a writes to any bit in the EFLAGS register.

Trait Implementations

impl Clone for Eflags

fn clone(&self) -> Eflags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Eflags

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

Formats the value using the given formatter.

impl Default for Eflags

fn default() -> Self

Returns the “default value” for a type.

impl Display for Eflags

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

Formats the value using the given formatter.

impl PartialEq for Eflags

fn eq(&self, other: &Eflags) -> 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 Copy for Eflags

impl StructuralPartialEq for Eflags
