Struct diskplan_schema::Expression

pub struct Expression<'t>(/* private fields */);

A string expression made from one or more Tokens

Implementations

impl<'t> Expression<'t>

pub fn tokens(&self) -> &[Token<'t>]

Provides access to the slice of tokens that make up this expression

Trait Implementations

impl<'t> Clone for Expression<'t>

fn clone(&self) -> Expression<'t>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'t> Debug for Expression<'t>

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

Formats the value using the given formatter.

impl Display for Expression<'_>

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

Formats the value using the given formatter.

impl<'t> From<&[Token<'t>]> for Expression<'t>

fn from(tokens: &[Token<'t>]) -> Self

Converts to this type from the input type.

impl<'a> From<Identifier<'a>> for Expression<'a>

fn from(identifier: Identifier<'a>) -> Self

Converts to this type from the input type.

impl<'t> From<Vec<Token<'t>>> for Expression<'t>

fn from(tokens: Vec<Token<'t>>) -> Self

Converts to this type from the input type.

impl<'t> Ord for Expression<'t>

fn cmp(&self, other: &Expression<'t>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq<&str> for Expression<'_>

fn eq(&self, other: &&str) -> 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<'t> PartialEq for Expression<'t>

fn eq(&self, other: &Expression<'t>) -> 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<'t> PartialOrd for Expression<'t>

fn partial_cmp(&self, other: &Expression<'t>) -> 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 le(&self, other: &Rhs) -> bool

This method tests less than or equal to (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.
