Struct arcdps_imgui::ImString

pub struct ImString(/* private fields */);

A UTF-8 encoded, growable, implicitly nul-terminated string.

Implementations

impl ImString

pub fn new<T: Into<String>>(value: T) -> ImString

Creates a new ImString from an existing string.

pub fn with_capacity(capacity: usize) -> ImString

Creates a new empty ImString with a particular capacity

pub unsafe fn from_utf8_unchecked(v: Vec<u8>) -> ImString

Converts a vector of bytes to a ImString without checking that the string contains valid UTF-8

Safety

It is up to the caller to guarantee the vector contains valid UTF-8 and no null terminator.

pub unsafe fn from_utf8_with_nul_unchecked(v: Vec<u8>) -> ImString

Converts a vector of bytes to a ImString without checking that the string contains valid UTF-8

Safety

It is up to the caller to guarantee the vector contains valid UTF-8 and a null terminator.

pub fn clear(&mut self)

Truncates this ImString, removing all contents

pub fn push(&mut self, ch: char)

Appends the given character to the end of this ImString

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

Appends a given string slice to the end of this ImString

pub fn capacity(&self) -> usize

Returns the capacity of this ImString in bytes

pub fn capacity_with_nul(&self) -> usize

Returns the capacity of this ImString in bytes, including the implicit null byte

pub fn reserve(&mut self, additional: usize)

Ensures that the capacity of this ImString is at least additional bytes larger than the current length.

The capacity may be increased by more than additional bytes.

pub fn reserve_exact(&mut self, additional: usize)

Ensures that the capacity of this ImString is at least additional bytes larger than the current length

pub fn as_ptr(&self) -> *const c_char

Returns a raw pointer to the underlying buffer

pub fn as_mut_ptr(&mut self) -> *mut c_char

Returns a raw mutable pointer to the underlying buffer.

If the underlying data is modified, refresh_len must be called afterwards.

pub unsafe fn refresh_len(&mut self)

Updates the underlying buffer length based on the current contents.

This function must be called if the underlying data is modified via a pointer obtained by as_mut_ptr.

Safety

It is up to the caller to guarantee the this ImString contains valid UTF-8 and a null terminator.

Methods from Deref<Target = ImStr>

pub fn as_ptr(&self) -> *const c_char

Converts an imgui-rs string slice to a raw pointer

pub fn to_str(&self) -> &str

Converts an imgui-rs string slice to a normal string slice

pub fn is_empty(&self) -> bool

Returns true if the imgui-rs string slice is empty
