Struct Mime 

pub struct Mime<T = Vec<(Attr, Value)>>(pub TopLevel, pub SubLevel, pub T)
where
    T: AsRef<[(Attr, Value)]>;

Mime, or Media Type. Encapsulates common registers types.

Consider that a traditional mime type contains a “top level type”, a “sub level type”, and 0-N “parameters”. And they’re all strings. Strings everywhere. Strings mean typos. Rust has type safety. We should use types!

So, Mime bundles together this data into types so the compiler can catch your typos.

This improves things so you use match without Strings:

use mime::{Mime, TopLevel, SubLevel};

let mime: Mime = "application/json".parse().unwrap();

match mime {
    Mime(TopLevel::Application, SubLevel::Json, _) => println!("matched json!"),
    _ => ()
}

Implementations

impl<P> Mime<P>

where P: AsRef<[(Attr, Value)]>,

pub fn get_param<A>(&self, attr: A) -> Option<&Value>

where A: PartialEq<Attr>,

Trait Implementations

impl<T> Clone for Mime<T>

where T: Clone + AsRef<[(Attr, Value)]>,

fn clone(&self) -> Mime<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Mime<T>

where T: Debug + AsRef<[(Attr, Value)]>,

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

Formats the value using the given formatter.

impl<T> Display for Mime<T>

where T: AsRef<[(Attr, Value)]>,

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

Formats the value using the given formatter.

impl FromStr for Mime

type Err = ()

The associated error which can be returned from parsing.

fn from_str(raw: &str) -> Result<Mime, ()>

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

impl<T> Hash for Mime<T>

where T: Hash + AsRef<[(Attr, Value)]>,

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<T> Ord for Mime<T>

where T: Ord + AsRef<[(Attr, Value)]>,

fn cmp(&self, other: &Mime<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<LHS, RHS> PartialEq<Mime<RHS>> for Mime<LHS>

where LHS: AsRef<[(Attr, Value)]>, RHS: AsRef<[(Attr, Value)]>,

fn eq(&self, other: &Mime<RHS>) -> 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<T> PartialOrd for Mime<T>

fn partial_cmp(&self, other: &Mime<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
