Struct PgLSeg 

pub struct PgLSeg {
    pub start_x: f64,
    pub start_y: f64,
    pub end_x: f64,
    pub end_y: f64,
}

Postgres Geometric Line Segment type

Description: Finite line segment Representation: ((start_x,start_y),(end_x,end_y))

Line segments are represented by pairs of points that are the endpoints of the segment. Values of type lseg are specified using any of the following syntaxes:

[ ( start_x , start_y ) , ( end_x , end_y ) ]
( ( start_x , start_y ) , ( end_x , end_y ) )
  ( start_x , start_y ) , ( end_x , end_y )
    start_x , start_y   ,   end_x , end_y

where (start_x,start_y) and (end_x,end_y) are the end points of the line segment.

See Postgres Manual, Section 8.8.3, Geometric Types - Line Segments for details.

Fields

start_x: f64

Trait Implementations

impl Clone for PgLSeg

fn clone(&self) -> PgLSeg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgLSeg

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

Formats the value using the given formatter.

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

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

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

impl Encode<'_, Postgres> for PgLSeg

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

fn encode_by_ref( &self, buf: &mut PgArgumentBuffer, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

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

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 PgLSeg

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

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl PartialEq for PgLSeg

fn eq(&self, other: &PgLSeg) -> 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 PgLSeg

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl Type<Postgres> for PgLSeg

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.
