Struct Method 

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

The Request Method (VERB)

This type also contains constants for a number of common HTTP methods such as GET, POST, etc.

Currently includes 8 variants representing the 8 methods defined in RFC 7230, plus PATCH, and an Extension variant for all extensions.

Examples

use http::Method;

assert_eq!(Method::GET, Method::from_bytes(b"GET").unwrap());
assert!(Method::GET.is_idempotent());
assert_eq!(Method::POST.as_str(), "POST");

Implementations

impl Method

pub const GET: Method

GET

pub const POST: Method

POST

pub const PUT: Method

PUT

pub const DELETE: Method

DELETE

pub const HEAD: Method

HEAD

pub const OPTIONS: Method

OPTIONS

pub const CONNECT: Method

CONNECT

pub const PATCH: Method

PATCH

pub const TRACE: Method

pub fn from_bytes(src: &[u8]) -> Result<Method, InvalidMethod>

Converts a slice of bytes to an HTTP method.

pub fn is_safe(&self) -> bool

Whether a method is considered “safe”, meaning the request is essentially read-only.

See the spec for more words.

pub fn is_idempotent(&self) -> bool

Whether a method is considered “idempotent”, meaning the request has the same result if executed multiple times.

See the spec for more words.

pub fn as_str(&self) -> &str

Return a &str representation of the HTTP method

Trait Implementations

impl AsRef<str> for Method

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Method

fn clone(&self) -> Method

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Method

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

Formats the value using the given formatter.

impl Default for Method

fn default() -> Method

Returns the “default value” for a type.

impl Display for Method

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

Formats the value using the given formatter.

impl<'a> From<&'a Method> for Method

fn from(t: &'a Method) -> Method

Converts to this type from the input type.

impl From<AccessControlRequestMethod> for Method

fn from(method: AccessControlRequestMethod) -> Method

Converts to this type from the input type.

impl From<Method> for AllowMethods

fn from(method: Method) -> AllowMethods

Converts to this type from the input type.

impl<S> FromRequestParts<S> for Method

where S: Send + Sync,

type Rejection = Infallible

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, _: &S, ) -> Result<Method, <Method as FromRequestParts<S>>::Rejection>

Perform the extraction.

impl FromStr for Method

type Err = InvalidMethod

The associated error which can be returned from parsing.

fn from_str(t: &str) -> Result<Method, <Method as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Method

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl OperationInput for Method

fn operation_input(ctx: &mut GenContext, operation: &mut Operation)

Modify the operation.

fn inferred_early_responses( ctx: &mut GenContext, operation: &mut Operation, ) -> Vec<(Option<u16>, Response)>

Inferred early responses are used to document early returns for extractors, guards inside handlers. For example these could represent JSON parsing errors, authentication failures.

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

impl<'a> PartialEq<&'a str> for Method

fn eq(&self, other: &&'a str) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

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

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

impl PartialEq<Method> for str

fn eq(&self, other: &Method) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

impl PartialEq<str> for Method

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

impl PartialEq for Method

fn eq(&self, other: &Method) -> bool

Tests for self and other values to be equal, and is used by ==.
