Function add_to_ngx_table

pub unsafe fn add_to_ngx_table(
    table: *mut ngx_table_elt_s,
    pool: *mut ngx_pool_s,
    key: impl AsRef<[u8]>,
    value: impl AsRef<[u8]>,
) -> Option<()>

Add a key-value pair to an nginx table entry (ngx_table_elt_t) in the given nginx memory pool.

Arguments

• table - A pointer to the nginx table entry (ngx_table_elt_t) to modify.
• pool - A pointer to the nginx memory pool (ngx_pool_t) for memory allocation.
• key - The key string to add to the table entry.
• value - The value string to add to the table entry.

Safety

This function is marked as unsafe because it involves raw pointer manipulation and direct memory allocation using str_to_uchar.

Returns

An Option<()> representing the result of the operation. Some(()) indicates success, while None indicates a null table pointer.

Example

// Obtain a pointer to the nginx table entry
let table: *mut ngx_table_elt_t = ngx_list_push(headers).cast();
assert!(!table.is_null());
let key: &str = "key"; // The key to add
let value: &str = "value"; // The value to add
let result = add_to_ngx_table(table, pool, key, value);
