Struct postgres_range::Range

pub struct Range<T> { /* fields omitted */ }

Represents a range of values.

Methods

impl<T> Range<T> where     T: PartialOrd + Normalizable,

pub fn new(     lower: Option<RangeBound<LowerBound, T>>,     upper: Option<RangeBound<UpperBound, T>> ) -> Range<T>

Creates a new range.

If a bound is None, the range is unbounded in that direction.

pub fn empty() -> Range<T>

Creates a new empty range.

pub fn is_empty(&self) -> bool

Determines if this range is the empty range.

pub fn lower(&self) -> Option<&RangeBound<LowerBound, T>>

Returns the lower bound if it exists.

pub fn upper(&self) -> Option<&RangeBound<UpperBound, T>>

Returns the upper bound if it exists.

pub fn contains(&self, value: &T) -> bool

Determines if a value lies within this range.

pub fn contains_range(&self, other: &Range<T>) -> bool

Determines if a range lies completely within this range.

impl<T> Range<T> where     T: PartialOrd + Normalizable + Clone,

pub fn intersect(&self, other: &Range<T>) -> Range<T>

Returns the intersection of this range with another.

pub fn union(&self, other: &Range<T>) -> Option<Range<T>>

Returns the union of this range with another if it is contiguous.

Trait Implementations

impl<T> FromSql for Range<T> where     T: PartialOrd + Normalizable + FromSql,

fn from_sql(ty: &Type, raw: &[u8]) -> Result<Range<T>, Box<Error + Sync + Send>>

Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null(ty: &Type) -> Result<Self, Box<Error + 'static + Send + Sync>>

Creates a new value of this type from a NULL SQL value.

fn from_sql_nullable(     ty: &Type,     raw: Option<&[u8]> ) -> Result<Self, Box<Error + 'static + Send + Sync>>

A convenience function that delegates to from_sql and from_sql_null depending on the value of raw.

impl<T> ToSql for Range<T> where     T: PartialOrd + Normalizable + ToSql,

fn to_sql(     &self,     ty: &Type,     buf: &mut Vec<u8> ) -> Result<IsNull, Box<Error + Sync + Send>>

Converts the value of self into the binary format of the specified Postgres Type, appending it to out.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be converted to the specified Postgres Type.

fn to_sql_checked(     &self,     ty: &Type,     out: &mut Vec<u8> ) -> Result<IsNull, Box<Error + Sync + Send>>

An adaptor method used internally by Rust-Postgres.

impl<T: Debug> Debug for Range<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Range<T>

fn eq(&self, other: &Range<T>) -> bool

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

fn ne(&self, other: &Range<T>) -> bool

This method tests for !=.

impl<T: Eq> Eq for Range<T>

impl<T: Clone> Clone for Range<T>

fn clone(&self) -> Range<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Copy> Copy for Range<T>

impl<T> Display for Range<T> where     T: Display,

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.
