Struct prql_compiler::ast::Ident

pub struct Ident {
    pub path: Vec<String>,
    pub name: String,
}

A name. Generally columns, tables, functions, variables. This is glorified way of writing a “vec with at least one element”.

Fields

path: Vec<String>

name: String

Implementations

impl Ident

pub fn from_name<S>(name: S) -> Ident

where S: ToString,

pub fn from_path<S>(path: Vec<S>) -> Ident

where S: ToString,

Creates a new ident from a non-empty path.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn pop(self) -> Option<Ident>

Remove last part of the ident. Result will generally refer to the parent of this ident.

pub fn pop_front(self) -> (String, Option<Ident>)

pub fn prepend(self, parts: Vec<String>) -> Ident

pub fn with_name<S>(self, name: S) -> Ident

where S: ToString,

pub fn iter(&self) -> impl Iterator<Item = &String>

pub fn starts_with(&self, prefix: &Ident) -> bool

pub fn starts_with_path<S>(&self, prefix: &[S]) -> bool

where S: AsRef<str>,

pub fn starts_with_part(&self, prefix: &str) -> bool

Trait Implementations

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Ident

fn deserialize<D>( deserializer: D, ) -> Result<Ident, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Ident

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

Formats the value using the given formatter.

impl From<Ident> for ExprKind

fn from(value: Ident) -> ExprKind

Converts to this type from the input type.

impl Hash for Ident

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 IntoIterator for Ident

type Item = String

The type of the elements being iterated over.

type IntoIter = Chain<IntoIter<String>, IntoIter<String>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <Ident as IntoIterator>::IntoIter

Creates an iterator from a value.

impl Ord for Ident

fn cmp(&self, other: &Ident) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Ident

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Ident

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Ident

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Ident
