Struct ngx_str_t

#[repr(C)]
pub struct ngx_str_t {
    pub len: usize,
    pub data: *mut u8,
}

Fields

len: usize

data: *mut u8

Implementations

impl ngx_str_t

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

Returns the contents of this ngx_str_t as a byte slice.

The returned slice will not contain the optional nul terminator that ngx_str_t.data may have.

pub fn as_bytes_mut(&mut self) -> &mut [u8]

Returns the contents of this ngx_str_t as a mutable byte slice.

pub fn is_empty(&self) -> bool

Returns true if the string has a length of 0.

pub fn to_str(&self) -> &str

Convert the nginx string to a string slice (&str).

Panics

This function panics if the ngx_str_t is not valid UTF-8.

Returns

A string slice (&str) representing the nginx string.

pub const fn empty() -> ngx_str_t

Creates an empty ngx_str_t instance.

This method replaces the ngx_null_string C macro.

pub unsafe fn from_bytes(pool: *mut ngx_pool_s, src: &[u8]) -> Option<ngx_str_t>

Create an ngx_str_t instance from a byte slice.

Safety

The caller must provide a valid pointer to a memory pool.

pub unsafe fn from_str(pool: *mut ngx_pool_s, data: &str) -> ngx_str_t

Create an ngx_str_t instance from a string slice (&str).

Arguments

• pool - A pointer to the nginx memory pool (ngx_pool_t).
• data - The string slice from which to create the nginx string.

Safety

This function is marked as unsafe because it accepts a raw pointer argument. There is no way to know if pool is pointing to valid memory. The caller must provide a valid pool to avoid indeterminate behavior.

Returns

An ngx_str_t instance representing the given string slice.
