Struct Array 

Source 
pub struct Array<T, const N: usize>(pub [T; N]);
Expand description

An extractor to handle fixed array contexts.

This struct allows you to deserialize arrays of context types from program entrypoint. Each element in the array is deserialized using the same HandlerContext::from_entrypoint method, consuming accounts and instruction data in sequence.

§Type Parameters

  • T: The context type
  • N: The compile-time constant size of the array

Tuple Fields§

§0: [T; N]
