Blanket Implementations

source

impl<T> Any for T where
T: 'static + ?Sized,

source

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source

impl<T> Borrow<T> for T where
T: ?Sized,

const: unstable · source

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

source

impl<T> BorrowMut<T> for T where
T: ?Sized,

const: unstable · source

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

source

impl<T> EasyArgumentField for T where
T: EasyArgumentGroup,

source

fn try_parse(
lookahead1: &Lookahead1<'_>,
stream: &ParseBuffer<'_>
) -> Result<Option<T>, Error>

Attempt to parse attribute field. Returns some field when parsing succeeds. Returns none if attribute peeking returns false, signalling that stream contains some other attribute. Returns error if peeking returns true but parsing fails. Read more

source

fn try_extend(
 &mut self,
 lookahead1: &Lookahead1<'_>,
 stream: &ParseBuffer<'_>
) -> Result<bool, Error>

Attempt to parse attribute field when it already has been successfully parsed. Field value should extend itself with newly parsed attribute or return error. Returns true when parsing and extending succeeds. Returns false if attribute peeking returns false, signalling that stream contains some other attribute. Returns error if peeking returns true but parsing or extending fails. Read more

source

fn missing() -> Result<T, String>

Called if the attribute field was never parsed. Returns error if attribute is mandatory. Otherwise returns an instance that will be used to build attributes structure. Read more

source

impl<T> EasyArgumentGroup for T where
T: EasyArgument,

source

fn try_parse(
lookahead1: &Lookahead1<'_>,
stream: &ParseBuffer<'_>
) -> Result<Option<T>, Error>

Attempt to parse attribute group. Returns some attribute when parsing succeeds. Returns none if attribute peeking returns false, signalling that stream contains some other attribute. Returns error if peeking returns true but parsing fails. Read more

source

fn overlap_error(&self, other: &T) -> Error

Produces error with appropriate message when the attribute group overlaps another instance. This is called by certain EasyArgumentField implementations. Read more

source

fn missing_error() -> String

Produces error with appropriate message when the attribute group is missing. This is called by certain EasyArgumentField implementations. Read more

source

impl<T> From<T> for T

const: unstable · source

fn from(t: T) -> T

Returns the argument unchanged.

source

impl<T, U> Into for T where
U: From<T>,

const: unstable · source

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source

impl<T> ToOwned for T where
T: Clone,

type Owned = T

The resulting type after obtaining ownership.

source

fn to_owned(&self) -> T

Creates owned data from borrowed data, usually by cloning. Read more

source

fn clone_into(&self, target: &mut T)

Uses borrowed data to replace owned data, usually by cloning. Read more

source

impl<T, U> TryFrom for T where
U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

const: unstable · source

fn try_from(value: U) -> Result<T, <T as TryFrom>::Error>

Performs the conversion.

source

impl<T, U> TryInto for T where
U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.
