Struct De9im 

pub struct De9im {
    pub m: [[Dimension; 3]; 3],
}

A DE-9IM 3×3 intersection matrix between two geometries.

Rows are the first geometry’s {Interior, Boundary, Exterior}, columns the second’s. m[r][c] is the dimension of the intersection of the first’s feature r with the second’s feature c. Mirrors Boost’s relate::matrix (detail/relate/result.hpp).

Fields

m: [[Dimension; 3]; 3]

[row][col] over [Interior, Boundary, Exterior].

Implementations

impl De9im

pub fn transposed(self) -> Self

Swap the two related geometries by transposing the matrix.

pub fn interior_interior(&self) -> Dimension

The [Interior][Interior] cell — do the two interiors meet, and in what dimension.

pub fn boundary_boundary(&self) -> Dimension

The [Boundary][Boundary] cell.

pub fn interior_exterior(&self) -> Dimension

The [Interior][Exterior] cell — is part of the first’s interior outside the second.

pub fn exterior_interior(&self) -> Dimension

The [Exterior][Interior] cell.

pub fn matches(&self, mask: &str) -> Result<bool, RelateError>

Test this matrix against a nine-character DE-9IM mask.

Mirrors Boost’s de9im::mask matching from algorithms/detail/relate/result.hpp:425-505: * accepts any cell, T accepts any non-empty cell, F accepts an empty cell, and 0/1/2 require an exact point/curve/area dimension.

Errors

Returns RelateError::InvalidMask unless mask contains exactly nine valid ASCII mask characters.
