Struct ttv_chat::maybe_owned::MaybeOwnedIndex

pub struct MaybeOwnedIndex {
    pub start: u16,
    pub end: u16,
}

An index into a MaybeOwned.

Fields

start: u16

The start index

end: u16

The end index

Implementations

impl MaybeOwnedIndex

pub const fn raw(start: usize, end: usize) -> MaybeOwnedIndex

Create a new index from this start and end point

pub const fn new(pos: usize) -> MaybeOwnedIndex

Create a new index with the same starting/ending point.

This has the end point to start -- so you can resize/bump/etc the end.

pub const fn offset_by(self, pos: usize) -> MaybeOwnedIndex

Shift the whole start/end pairs by pos amount

pub const fn resize(self, len: usize) -> MaybeOwnedIndex

Grow the end by len amount

pub const fn truncate(self, len: usize) -> MaybeOwnedIndex

Shrink the end by len amount

pub fn replace(&mut self, pos: usize) -> MaybeOwnedIndex

Replace this index with a new one start/ending at pos, returning the old index

pub const fn is_empty(&self) -> bool

Checks whether this index is empty (e.g. start points to the dn)

pub fn bump_tail(&mut self)

Bump the 'end' by 1 unit

pub const fn as_range(self) -> Range<usize>

Get this type as a range
