Struct XgLine 

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

Xugu 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.

Fields

a: f64

b: f64

c: f64

Implementations

impl XgLine

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Trait Implementations

impl Clone for XgLine

fn clone(&self) -> XgLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for XgLine

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

Formats the value using the given formatter.

impl<'r> Decode<'r, Xugu> for XgLine

fn decode(value: XuguValueRef<'r>) -> Result<Self, BoxDynError>

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

impl Display for XgLine

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

Formats the value using the given formatter.

impl Encode<'_, Xugu> for XgLine

fn encode_by_ref( &self, args: &mut Vec<XuguArgumentValue<'_>>, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

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

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> 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 XgLine

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 XgLine

fn eq(&self, other: &XgLine) -> 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 Type<Xugu> for XgLine

fn type_info() -> XuguTypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &XuguTypeInfo) -> bool

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