Struct HandleInfo

#[repr(C)]
pub struct HandleInfo {
    pub handle: Handle,
    pub object_type: ObjectType,
    pub rights: Rights,
    /* private fields */
}

Information on handles that were read.

ABI-compatible with zx_handle_info_t.

Fields

handle: Handle

object_type: ObjectType

rights: Rights

Implementations

impl HandleInfo

pub const fn new( handle: Handle, object_type: ObjectType, rights: Rights, ) -> HandleInfo

Make a new HandleInfo.

pub const unsafe fn from_raw(raw: zx_handle_info_t) -> HandleInfo

Safety

See Handle::from_raw for requirements about the validity and closing of raw.handle.

Note that while raw.ty should correspond to the type of the handle, that this is not required for safety.

Trait Implementations

impl Debug for HandleInfo

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

Formats the value using the given formatter.

impl HandleInfoFor<DefaultFuchsiaResourceDialect> for HandleInfo

fn consume( &mut self, expected_object_type: ObjectType, expected_rights: Rights, ) -> Result<Handle>

Verifies a HandleInfo has the type and rights we expect and extracts the D::Handle from it.

fn drop_in_place(&mut self)

Destroy the given handle info, leaving it invalid.

impl Hash for HandleInfo

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for HandleInfo

fn cmp(&self, other: &HandleInfo) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for HandleInfo

fn eq(&self, other: &HandleInfo) -> 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 PartialOrd for HandleInfo

fn partial_cmp(&self, other: &HandleInfo) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
