Enum Access

pub enum Access<'a> {
    Field(Cow<'a, str>),
    FieldIndex(usize),
    TupleIndex(usize),
    ListIndex(usize),
}

A singular element access within a path. Multiple accesses can be combined into a ParsedPath.

Can be applied to a dyn Reflect to get a reference to the targeted element.

Variants

Field(Cow<'a, str>)

A name-based field access on a struct.

FieldIndex(usize)

A index-based field access on a struct.

TupleIndex(usize)

An index-based access on a tuple.

ListIndex(usize)

An index-based access on a list.

Implementations

impl<'a> Access<'a>

pub fn into_owned(self) -> Access<'static>

Converts this into an “owned” value.

If the Access is of variant Field, the field’s Cow<str> will be converted to its owned counterpart, which doesn’t require a reference.

pub fn display_value(&self) -> &dyn Display

Returns a reference to this Access’s inner value as a &dyn Display.

Trait Implementations

impl<'a> Clone for Access<'a>

fn clone(&self) -> Access<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Access<'a>

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

Formats the value using the given formatter.

impl Display for Access<'_>

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

Formats the value using the given formatter.

impl From<Access<'static>> for OffsetAccess

fn from(access: Access<'static>) -> Self

Converts to this type from the input type.

impl<'a> Hash for Access<'a>

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

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<'a> Ord for Access<'a>

fn cmp(&self, other: &Access<'a>) -> 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<'a> PartialEq for Access<'a>

fn eq(&self, other: &Access<'a>) -> 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<'a> PartialOrd for Access<'a>

fn partial_cmp(&self, other: &Access<'a>) -> Option<Ordering>

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

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

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

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

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.
