Struct MaybeStructured

pub struct MaybeStructured<'a, T>
where
    T: ?Sized,
{ /* private fields */ }

A wrapper around a generic type that can be used to construct for insertion.

Implementations

impl<'a, T> MaybeStructured<'a, T>

where T: 'a + Type + ?Sized,

pub fn encoded_len(&self) -> usize

Returns the encoded length.

pub fn encode(&self, buf: &mut [u8]) -> Result<usize, <T as Type>::Error>

Encodes the generic into the buffer.

Panics

• if the buffer is not large enough.

pub fn encode_to_buffer( &self, buf: &mut VacantBuffer<'_>, ) -> Result<usize, <T as Type>::Error>

Encodes the generic into the given buffer.

Panics

• if the buffer is not large enough.

impl<'a, T> MaybeStructured<'a, T>

where T: 'a + ?Sized,

pub const fn data(&self) -> Either<&'a T, &'a [u8]>

Returns the value contained in the generic.

pub const unsafe fn from_slice(slice: &'a [u8]) -> MaybeStructured<'a, T>

Creates a new unstructured MaybeStructured from bytes for querying or inserting.

Safety

• the slice must the same as the one returned by T::encode.

impl<'a, T> Debug for MaybeStructured<'a, T>

fn cmp(&self, other: &MaybeStructured<'a, T>) -> 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.
