Struct BigVec 

pub struct BigVec<'data> {
    pub data: &'data mut [u8],
}

Contains easy to use utilities for a big vector of Borsh-compatible types, to avoid managing the entire struct on-chain and blow through stack limits.

Fields

data: &'data mut [u8]

Underlying data buffer, pieces of which are serialized

Implementations

impl BigVec<'_>

pub fn len(&self) -> u32

Get the length of the vector

pub fn is_empty(&self) -> bool

Find out if the vector has no contents

pub fn retain<T: Pod, F: Fn(&[u8]) -> bool>( &mut self, predicate: F, ) -> Result<(), ProgramError>

Retain all elements that match the provided function, discard all others

pub fn deserialize_mut_slice<T: Pod>( &mut self, skip: usize, len: usize, ) -> Result<&mut [T], ProgramError>

Extracts a slice of the data types

pub fn deserialize_slice<T: Pod>( &self, skip: usize, len: usize, ) -> Result<&[T], ProgramError>

Extracts a slice of the data types

pub fn push<T: Pod>(&mut self, element: T) -> Result<(), ProgramError>

Add new element to the end

pub fn find<T: Pod, F: Fn(&[u8]) -> bool>(&self, predicate: F) -> Option<&T>

Find matching data in the array

pub fn find_mut<T: Pod, F: Fn(&[u8]) -> bool>( &mut self, predicate: F, ) -> Option<&mut T>

Find matching data in the array
