Struct MmapStringArray 

pub struct MmapStringArray<const N: usize, const LEN: usize> { /* private fields */ }

A fixed-size array of fixed-size strings for memory-mapped storage

Implementations

impl<const N: usize, const LEN: usize> MmapStringArray<N, LEN>

pub fn new() -> Self

Create a new array of empty strings

pub fn get(&self, index: usize) -> Option<&str>

Get a string by index

pub fn set(&mut self, index: usize, value: &str) -> bool

Set a string at index

pub fn get_mut(&mut self, index: usize) -> Option<&mut MmapString<LEN>>

Get mutable access to a string

pub fn clear(&mut self)

Clear all strings

pub fn count_non_empty(&self) -> usize

Get the number of non-empty strings

pub fn iter(&self) -> impl Iterator<Item = &str>

Iterate over all strings

pub fn len(&self) -> usize

Get the capacity (number of strings)

pub fn is_empty(&self) -> bool

Check if array is empty (always false for non-zero N)

Trait Implementations

impl<const N: usize, const LEN: usize> Default for MmapStringArray<N, LEN>

fn default() -> Self

Returns the “default value” for a type.

impl<const N: usize, const LEN: usize> Index<usize> for MmapStringArray<N, LEN>

type Output = MmapString<LEN>
