Struct Params 

pub struct Params<'a> { /* private fields */ }

Borrowed view of a CSI / DCS parameter body.

Implementations

impl<'a> Params<'a>

pub const EMPTY: Self

Empty parameter list.

pub fn from_raw(raw: &'a [u8]) -> Self

Wrap the raw parameter bytes (between the introducer’s last byte and the final byte, exclusive on both ends).

pub fn raw(&self) -> &'a [u8]

The raw parameter bytes, exactly as they appeared on the wire.

pub fn is_empty(&self) -> bool

true when the parameter body is empty (no groups at all).

pub fn len(&self) -> usize

Number of ;-separated groups. An empty body has zero groups; a trailing ; produces an extra empty group.

pub fn iter(&self) -> ParamIter<'a>

Sequential iterator over the ;-separated groups.

pub fn group(&self, idx: usize) -> Option<Group<'a>>

The n-th group, or None when idx >= len().

pub fn get(&self, idx: usize) -> Option<u32>

First sub-parameter of the n-th group. None for absent groups and explicitly empty slots.

pub fn get_or(&self, idx: usize, default: u32) -> u32

First sub-parameter of the n-th group, or default when the group is absent or the slot is explicitly empty.

pub fn slice_from(&self, start: usize) -> Params<'a>

A Params view starting at the group at index start. Used when a caller needs to expose “the rest of the parameter list” (e.g. Event::WindowOp’s args).

Trait Implementations

impl<'a> Clone for Params<'a>

fn clone(&self) -> Params<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Params<'a>

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

Formats the value using the given formatter.

impl<'a> IntoIterator for Params<'a>

type Item = Group<'a>

The type of the elements being iterated over.

type IntoIter = ParamIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
