Struct FetchOptions 

#[non_exhaustive]
pub struct FetchOptions {
    pub headers: HashMap<String, String>,
    /* private fields */
}

Options on how fetches should be made.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

headers: HashMap<String, String>

Custom headers to pass into fetch request. Headers must have a maximum of 3 key value pairs. Each key value pair must have a maximum of 256 characters per key and 256 characters per value.

Implementations

impl FetchOptions

pub fn new() -> Self

Creates a new default instance.

pub fn set_headers<T, K, V>(self, v: T) -> Self

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Sets the value of headers.

Example

let x = FetchOptions::new().set_headers([
    ("key0", "abc"),
    ("key1", "xyz"),
]);

Trait Implementations

impl Clone for FetchOptions

fn clone(&self) -> FetchOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FetchOptions

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

Formats the value using the given formatter.

impl Default for FetchOptions

fn default() -> FetchOptions

Returns the “default value” for a type.

impl Message for FetchOptions

fn typename() -> &'static str

The typename of this message.

impl PartialEq for FetchOptions

fn eq(&self, other: &FetchOptions) -> 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.
