Struct PgCircle

pub struct PgCircle {
    pub x: f64,
    pub y: f64,
    pub radius: f64,
}

Available on crate feature postgres only.

Postgres Geometric Circle type

Description: Circle Representation: < (x, y), radius > (center point and radius)

< ( x , y ) , radius >
( ( x , y ) , radius )
  ( x , y ) , radius
    x , y   , radius

where (x,y) is the center point.

See Postgres Manual, Section 8.8.7, Geometric Types - Circles for details.

Fields

x: f64

y: f64

radius: f64

Trait Implementations

impl Clone for PgCircle

fn clone(&self) -> PgCircle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PgCircle

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

Formats the value using the given formatter.

impl<'r> Decode<'r, Postgres> for PgCircle

fn decode( value: PgValueRef<'r>, ) -> Result<PgCircle, Box<dyn Error + Sync + Send>>

Decode a new value of this type using a raw value from the database.

impl<'q> Encode<'q, Postgres> for PgCircle

fn produces(&self) -> Option<PgTypeInfo>

fn encode_by_ref( &self, buf: &mut PgArgumentBuffer, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

Writes the value of self into buf without moving self.

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn size_hint(&self) -> usize

impl FromStr for PgCircle

type Err = Box<dyn Error + Sync + Send>

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<PgCircle, <PgCircle as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for PgCircle

fn eq(&self, other: &PgCircle) -> 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 PgHasArrayType for PgCircle

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl Type<Postgres> for PgCircle

fn type_info() -> PgTypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &<DB as Database>::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.
