Struct compact::CString

pub struct CString { /* fields omitted */ }

A compact storage for a String. So far doesn't support direct mutable operations, Only conversion from and to String/&str

Methods

impl CompactString

pub fn new() -> Self

Create an empty CString

pub fn push_str(&mut self, string: &str)

Appends a given string slice onto the end of this CString.

Trait Implementations

impl Compact for CompactString

fn is_still_compact(&self) -> bool

Is the object's dynamic part stored compactly?

fn dynamic_size_bytes(&self) -> usize

Size of the dynamic part in bytes

unsafe fn compact(source: *mut Self, dest: *mut Self, new_dynamic_part: *mut u8)

Copy the static part of source to dest and compactly store the dynamic part of source as the new dynamic part of dest at new_dynamic_part. This semantically moves source into dest.

unsafe fn decompact(source: *const Self) -> Self

Creates a clone of self with the dynamic part guaranteed to be stored freely.

fn total_size_bytes(&self) -> usize

Total size of the object (static part + dynamic part)

unsafe fn behind(ptr: *mut Self) -> *mut u8

Get a pointer to behind the static part of self (commonly used place for the dynamic part)

unsafe fn compact_behind(source: *mut Self, dest: *mut Self)

Like compact with new_dynamic_part set to dest.behind()

impl Default for CompactString

fn default() -> CompactString

Returns the "default value" for a type.

impl From<String> for CompactString

fn from(string: String) -> CompactString

Performs the conversion.

impl Clone for CompactString

fn clone(&self) -> CompactString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Deref for CompactString

type Target = str

The resulting type after dereferencing.

fn deref(&self) -> &str

Dereferences the value.
