Trait generic_array::sequence::GenericSequence

pub unsafe trait GenericSequence<T>: Sized + IntoIterator {
    type Length: ArrayLength;
    type Sequence: GenericSequence<T, Length = Self::Length> + FromIterator<T>;

    // Required method
    fn generate<F>(f: F) -> Self::Sequence
       where F: FnMut(usize) -> T;
}

Defines some sequence with an associated length and iteration capabilities.

This is useful for passing N-length generic arrays as generics.

Safety

Care must be taken when implementing such that methods are safe.

Lengths must match, and element drop on panic must be handled.

Required Associated Types

type Length: ArrayLength

GenericArray associated length

type Sequence: GenericSequence<T, Length = Self::Length> + FromIterator<T>

Owned sequence type used in conjuction with reference implementations of GenericSequence

Required Methods

fn generate<F>(f: F) -> Self::Sequence

where F: FnMut(usize) -> T,

Initializes a new sequence instance using the given function.

If the generator function panics while initializing the sequence, any already initialized elements will be dropped.

Object Safety

This trait is not object safe.
