Interface IGrowableBuffer<T>

Represents common interface for growable buffer writers.

Inherited Members
Namespace: DotNext.Buffers
Assembly: DotNext.dll
Syntax
public interface IGrowableBuffer<T> : IReadOnlySpanConsumer<T>, ISupplier<ReadOnlyMemory<T>, CancellationToken, ValueTask>, IFunctional<Func<ReadOnlyMemory<T>, CancellationToken, ValueTask>>, IDisposable, IResettable
Type Parameters
Name Description
T

The type of the elements in the buffer.
Remarks

This interface is intended to describe the shape of all buffer writer types in .NEXT family of libraries. It is not recommended to have custom implementation of this interface in your code.
