Struct TaskCommand 

pub struct TaskCommand { /* private fields */ }

The command for a task.

Linux task commands are limited to 15 bytes, but Fuchsia allows longer names in places. It’s useful to store longer names diagnostics and debugging information.

Implementations

impl TaskCommand

pub fn new(name: &[u8]) -> Self

Create a new TaskCommand from a byte slice. The byte slice is truncated at the first null byte if any.

pub fn from_path_bytes(path: &[u8]) -> Self

Create a new TaskCommand from a path. The basename of the path is used as the name.

pub fn comm_name(&self) -> &[u8]

Returns the name truncated to 15 bytes.

pub fn prctl_name(&self) -> [u8; 16]

Returns the name as a 16-byte array, null-terminated if shorter than 16 bytes, as expected by prctl(PR_GET_NAME).

pub fn as_bytes(&self) -> &[u8]

Returns the entire name as a byte slice.

pub fn try_embed(&self, other: &TaskCommand) -> Option<Self>

Tries to embed other as the Linux name within this command. Returns a new TaskCommand if other is a substring of this command.

Trait Implementations

impl Clone for TaskCommand

fn clone(&self) -> TaskCommand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskCommand

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

Formats the value using the given formatter.

impl Default for TaskCommand

fn default() -> Self

Returns the “default value” for a type.

impl Display for TaskCommand

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

Formats the value using the given formatter.

impl Hash for TaskCommand

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

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 Into<FlyByteStr> for TaskCommand

fn into(self) -> FlyByteStr

Converts this type into the (usually inferred) input type.

impl Ord for TaskCommand

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

This comparison ignores the linux rendering of the name and provides a total ordering based on the full name.

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 TaskCommand

fn eq(&self, other: &TaskCommand) -> 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 TaskCommand

fn partial_cmp(&self, other: &Self) -> 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.
