Struct PgLine 

pub struct PgLine {
    pub a: f64,
    pub b: f64,
    pub c: f64,
}

Available on crate feature postgres only.

Postgres Geometric Line type

Description: Infinite line Representation: {A, B, C}

Lines are represented by the linear equation Ax + By + C = 0, where A and B are not both zero.

See Postgres Manual, Section 8.8.2, Geometric Types - Lines for details.

Fields

a: f64

b: f64

c: f64

Trait Implementations

impl Clone for PgLine

fn clone(&self) -> PgLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgLine

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

Formats the value using the given formatter.

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

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

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

impl Encode<'_, Postgres> for PgLine

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

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

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 PgLine

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

The associated error which can be returned from parsing.

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

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

impl PartialEq for PgLine

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

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl Type<Postgres> for PgLine

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.

impl StructuralPartialEq for PgLine
