Struct AttributePath 

pub struct AttributePath {
    pub steps: Vec<AttributePathStep>,
}

Represent the path to an attribute

Example

let path = AttributePath::new("foo").key("bar").attribute("array").index(1);
// foo["bar"].array[1]

Fields

steps: Vec<AttributePathStep>

Implementations

impl AttributePath

pub fn new<T: Into<Cow<'static, str>>>(name: T) -> Self

Create a new attribute path with the root attribute

Arguments

• name - Name of the root attribute

pub fn root() -> Self

Create a new attribute path without any path component

pub fn function_argument(index: i64) -> Self

Create a new attribute path for a function argument

Arguments

• index - index of the function argument

pub fn attribute<T: Into<Cow<'static, str>>>(self, name: T) -> Self

Create a new attribute path where the attribute .name has been appended

Arguments

• name - name of the attribute

pub fn key<T: Into<Cow<'static, str>>>(self, key: T) -> Self

Create a new attribute path where the access ["key"] has been appended

Arguments

• key - string subscript

pub fn index<T: Into<i64>>(self, idx: T) -> Self

Create a new attribute path where the access [idx] has been appended

Arguments

• idx - integer subscript

pub fn add_attribute<T: Into<Cow<'static, str>>>( &mut self, name: T, ) -> &mut Self

Add name access to the path (ie: .name)

Arguments

• name - name of the attribute

pub fn add_key<T: Into<Cow<'static, str>>>(&mut self, key: T) -> &mut Self

add key access to the path (ie: ["key"])

Arguments

• key - string subscript

pub fn add_index<T: Into<i64>>(&mut self, idx: T) -> &mut Self

add index access to the path (ie: [idx])

Arguments

• idx - integer subscript

pub fn add_step(&mut self, step: AttributePathStep) -> &mut Self

Add step to the path

Arguments

• step - step to add

pub fn add_steps(&mut self, steps: AttributePath) -> &mut Self

Add multiple steps into the path

Arguments

• steps - steps to add

Trait Implementations

impl Add<AttributePathStep> for AttributePath

type Output = AttributePath

The resulting type after applying the + operator.

fn add(self, rhs: AttributePathStep) -> Self::Output

Performs the + operation.

impl AddAssign<AttributePathStep> for AttributePath

fn add_assign(&mut self, rhs: AttributePathStep)

Performs the += operation.

impl Clone for AttributePath

fn clone(&self) -> AttributePath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributePath

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

Formats the value using the given formatter.

impl Default for AttributePath

fn default() -> AttributePath

Returns the “default value” for a type.

impl Display for AttributePath

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

Formats the value using the given formatter.

impl Eq for AttributePath

impl From<AttributePathStep> for AttributePath

fn from(value: AttributePathStep) -> Self

Converts to this type from the input type.

impl Hash for AttributePath

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 PartialEq for AttributePath

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