Struct PgCube 

pub struct PgCube {
    pub coordinates: Vec<f64>,
    pub is_point: bool,
}

PostgreSQL CUBE type – an n-dimensional point or box.

CUBE is a PostgreSQL extension type for multi-dimensional geometric data. It represents either a point (all dimensions equal) or a box (two corners).

Binary wire format:

• ndim (u32): number of dimensions
• flags (u32): bit 0 = is_point
• coordinates: ndim f64 values for points, ndim * 2 for boxes

Uses TEXT OID as carrier since CUBE is an extension type.

Fields

coordinates: Vec<f64>

For a point: [x, y, z, ...] (ndim values). For a box: [x1, y1, z1, ..., x2, y2, z2, ...] (ndim * 2 values).

is_point: bool

True if this represents a point, false if a box.

Implementations

impl PgCube

pub fn point(coordinates: Vec<f64>) -> Self

Create a point with the given coordinates.

pub fn cube(coordinates: Vec<f64>, ndim: usize) -> Self

Create a box with the given coordinates and number of dimensions.

coordinates must have exactly ndim * 2 values: the first ndim are the lower-left corner, the last ndim are the upper-right.

pub fn ndim(&self) -> usize

Number of dimensions.

Trait Implementations

impl Clone for PgCube

fn clone(&self) -> PgCube

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgCube

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

Formats the value using the given formatter.

impl Display for PgCube

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

Formats the value using the given formatter.

impl FromSql for PgCube

fn oid() -> Oid

The PostgreSQL type OID this decoder handles.

fn from_sql(buf: &[u8]) -> Result<Self>

Decode from PG binary format.

fn from_sql_nullable(buf: Option<&[u8]>) -> Result<Self>

Decode from a potentially NULL column.

impl PartialEq for PgCube

fn eq(&self, other: &PgCube) -> 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 ToSql for PgCube

fn oid(&self) -> Oid

The PostgreSQL type OID for this Rust type.

fn to_sql(&self, buf: &mut BytesMut) -> Result<()>

Encode this value into PG binary format, appending to buf.

fn to_sql_vec(&self) -> Result<Vec<u8>>

Encode this value into a standalone byte vector for use as a bind parameter.

fn is_null(&self) -> bool

Returns true if this value represents SQL NULL.
