Struct Vecx 

pub struct Vecx<T> { /* private fields */ }

A disk-based, Vec-like data structure with typed values.

Vecx stores a sequence of values on disk, encoding them for persistence.

Implementations

impl<T: ValueEnDe> Vecx<T>

pub unsafe fn shadow(&self) -> Self

Creates a “shadow” copy of the Vecx instance.

Safety

This API breaks Rust’s semantic safety guarantees. Use only in a race-free environment.

pub unsafe fn from_bytes(s: impl AsRef<[u8]>) -> Self

Creates a Vecx from a byte slice.

Safety

This function is unsafe and assumes the byte slice is a valid representation.

pub fn as_bytes(&self) -> &[u8]

Returns the byte representation of the Vecx.

pub fn new() -> Self

Creates a new, empty Vecx.

pub fn get(&self, idx: usize) -> Option<T>

Retrieves a value at a specific index.

pub fn get_mut(&mut self, idx: usize) -> Option<ValueMut<'_, T>>

Retrieves a mutable reference to a value at a specific index.

pub fn last(&self) -> Option<T>

Retrieves the last value in the vector.

pub fn len(&self) -> usize

Returns the number of values in the vector.

pub fn is_empty(&self) -> bool

Checks if the vector is empty.

pub fn push(&mut self, v: &T)

Appends a value to the end of the vector.

pub fn insert(&mut self, idx: usize, v: &T)

Inserts a value at a specific index.

Panics

Panics if idx is out of bounds.

pub fn pop(&mut self) -> Option<T>

Removes and returns the last value in the vector.

pub fn remove(&mut self, idx: usize) -> T

Removes and returns the value at a specific index.

Panics

Panics if idx is out of bounds.

pub fn swap_remove(&mut self, idx: usize) -> T

Removes a value at a specific index and returns it, replacing it with the last value.

Panics

Panics if idx is out of bounds.

pub fn update(&mut self, idx: usize, v: &T) -> Option<T>

Updates the value at a specific index.

Panics

Panics if idx is out of bounds.

pub fn iter(&self) -> VecxIter<'_, T>

Returns an iterator over the vector’s values.

pub fn iter_mut(&mut self) -> VecxIterMut<'_, T>

Returns a mutable iterator over the vector’s values.

pub fn clear(&mut self)

Clears the vector, removing all values.

pub fn is_the_same_instance(&self, other_hdr: &Self) -> bool

Checks if this Vecx instance is the same as another.

Trait Implementations

impl<T> Clone for Vecx<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for Vecx<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: ValueEnDe> Default for Vecx<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Vecx<T>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: PartialEq> PartialEq for Vecx<T>

fn eq(&self, other: &Vecx<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Serialize for Vecx<T>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
