Implementations

impl<'a, T, S> BufferViewExample<'a, T, S>

Common methods.

pub const fn len(&self) -> NonValueU8<{ u8::MAX }>

Returns the number of elements currently stored in the buffer.

pub const fn len_prim(&self) -> u8

Returns the number of elements currently stored in the buffer.

pub const fn is_empty(&self) -> bool

Returns true if the buffer contains no elements.

impl<'a, T> BufferViewExample<'a, T, &'a mut [T]>

Buffer view over an exclusive slice.

Invariants

• Elements are stored in storage[0 .. len)
• len <= storage.len()

Notes

• This type does not own its elements
• Shrinking the buffer does not drop values, but mutating may overwrite.

pub const fn try_new(slice: &'a mut [T]) -> Option<Self>

Creates an empty buffer using the entire slice as backing storage.

Returns None if the slice length cannot be represented by the index type.

pub const fn new_truncated(slice: &'a mut [T]) -> Self

Creates an empty buffer, truncating the backing slice if it exceeds what the index type can represent.

pub const fn try_from_slice(slice: &'a mut [T]) -> Option<Self>

Creates a buffer over an exclusive slice.

Returns None if the slice length cannot be represented by the index type.

pub const fn from_slice_with( slice: &'a mut [T], len: NonValueU8<{ u8::MAX }>, ) -> Option<Self>

Creates a buffer over an exclusive slice with an explicit logical length.

Returns None if len > slice.len() or cannot be represented by the index type.

Creates a buffer over an exclusive slice, truncating the visible active range if the slice length exceeds what the index type can represent.
