Struct XgPath 

pub struct XgPath {
    pub closed: bool,
    pub points: Vec<XgPoint>,
}

Xugu Geometric Path type

Description: Open path or Closed path (similar to polygon) Representation: Open [(x1,y1),...], Closed ((x1,y1),...)

Paths are represented by lists of connected points. Paths can be open, where the first and last points in the list are considered not connected, or closed, where the first and last points are considered connected. Values of type path are specified using any of the following syntaxes:

[ ( x1 , y1 ) , ... , ( xn , yn ) ]
( ( x1 , y1 ) , ... , ( xn , yn ) )
  ( x1 , y1 ) , ... , ( xn , yn )
  ( x1 , y1   , ... ,   xn , yn )
    x1 , y1   , ... ,   xn , yn

where the points are the end points of the line segments comprising the path. Square brackets ([]) indicate an open path, while parentheses (()) indicate a closed path. When the outermost parentheses are omitted, as in the third through fifth syntaxes, a closed path is assumed.

Fields

closed: bool

points: Vec<XgPoint>

Implementations

Trait Implementations

impl Clone for XgPath

fn clone(&self) -> XgPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for XgPath

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

Formats the value using the given formatter.

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

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 XgPath

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

Formats the value using the given formatter.

impl Encode<'_, Xugu> for XgPath

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 XgPath

type Err = Error

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 XgPath

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

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.
