pub struct GeometryWalker<'r, R: BorrowedReader + 'r> { /* private fields */ }

Walker for a revisioned enum. Generated by #[revisioned(...)].

Implementations

impl<'r, R: BorrowedReader + 'r> GeometryWalker<'r, R>

pub fn revision(&self) -> u16

Wire revision of the encoded value being walked.

pub fn discriminant(&self) -> u32

Variant discriminant on the wire (for Wire) or on the re-encoded current-rev bytes (for the borrowed / owned arms). Use walk_revisioned_variant_name to map this to a variant identifier.

pub fn is_point(&self) -> bool

Returns true if the wire’s discriminant identifies this variant at the wire revision (or, for borrowed / owned walkers, on the current-rev bytes).

pub fn into_point( self, ) -> Result<<Point<f64> as WalkRevisioned>::Walker<'r, R>, Error>

Walk into the payload of the #variant_ident variant.

Errors with revision::Error::Deserialize if the wire encoding does not identify this variant. Errors with revision::Error::Conversion in materialised mode (older-rev convert_fn types); callers should use decode_<variant> in that case.

pub fn decode_point(self) -> Result<Point<f64>, Error>

Decode and return the inner value of the #variant_ident variant directly. Unlike into_<variant>, this works on every repr (Wire, OptimisedBorrowed, ConvertedOwned) because it deserialises by value rather than handing back a sub-walker.

pub fn point_view(self) -> Result<VariantView<'r, Point<f64>>, Error>

Return the variant payload as a VariantView.

Works on every repr. OptimisedBorrowed (the common optimised-enum case) hands back a borrowed slice with the source’s 'r lifetime — no allocation. Wire walkers re-encode (one allocation); ConvertedOwned (cross-revision convert_fn) walkers move the owned bytes.

Use decode_<variant> when you want the inner type by value directly.

pub fn is_line(&self) -> bool

Returns true if the wire’s discriminant identifies this variant at the wire revision (or, for borrowed / owned walkers, on the current-rev bytes).

pub fn into_line( self, ) -> Result<<LineString<f64> as WalkRevisioned>::Walker<'r, R>, Error>

Walk into the payload of the #variant_ident variant.

Errors with revision::Error::Deserialize if the wire encoding does not identify this variant. Errors with revision::Error::Conversion in materialised mode (older-rev convert_fn types); callers should use decode_<variant> in that case.

pub fn decode_line(self) -> Result<LineString<f64>, Error>

Decode and return the inner value of the #variant_ident variant directly. Unlike into_<variant>, this works on every repr (Wire, OptimisedBorrowed, ConvertedOwned) because it deserialises by value rather than handing back a sub-walker.

pub fn line_view(self) -> Result<VariantView<'r, LineString<f64>>, Error>

Return the variant payload as a VariantView.

Works on every repr. OptimisedBorrowed (the common optimised-enum case) hands back a borrowed slice with the source’s 'r lifetime — no allocation. Wire walkers re-encode (one allocation); ConvertedOwned (cross-revision convert_fn) walkers move the owned bytes.

Use decode_<variant> when you want the inner type by value directly.

pub fn is_polygon(&self) -> bool

Returns true if the wire’s discriminant identifies this variant at the wire revision (or, for borrowed / owned walkers, on the current-rev bytes).

pub fn into_polygon( self, ) -> Result<<Polygon<f64> as WalkRevisioned>::Walker<'r, R>, Error>

Walk into the payload of the #variant_ident variant.

Errors with revision::Error::Deserialize if the wire encoding does not identify this variant. Errors with revision::Error::Conversion in materialised mode (older-rev convert_fn types); callers should use decode_<variant> in that case.

pub fn decode_polygon(self) -> Result<Polygon<f64>, Error>

Decode and return the inner value of the #variant_ident variant directly. Unlike into_<variant>, this works on every repr (Wire, OptimisedBorrowed, ConvertedOwned) because it deserialises by value rather than handing back a sub-walker.

pub fn polygon_view(self) -> Result<VariantView<'r, Polygon<f64>>, Error>

Return the variant payload as a VariantView.

Works on every repr. OptimisedBorrowed (the common optimised-enum case) hands back a borrowed slice with the source’s 'r lifetime — no allocation. Wire walkers re-encode (one allocation); ConvertedOwned (cross-revision convert_fn) walkers move the owned bytes.

Use decode_<variant> when you want the inner type by value directly.

pub fn is_multi_point(&self) -> bool

Returns true if the wire’s discriminant identifies this variant at the wire revision (or, for borrowed / owned walkers, on the current-rev bytes).

pub fn into_multi_point( self, ) -> Result<<MultiPoint<f64> as WalkRevisioned>::Walker<'r, R>, Error>

Walk into the payload of the #variant_ident variant.

Errors with revision::Error::Deserialize if the wire encoding does not identify this variant. Errors with revision::Error::Conversion in materialised mode (older-rev convert_fn types); callers should use decode_<variant> in that case.

pub fn decode_multi_point(self) -> Result<MultiPoint<f64>, Error>

Decode and return the inner value of the #variant_ident variant directly. Unlike into_<variant>, this works on every repr (Wire, OptimisedBorrowed, ConvertedOwned) because it deserialises by value rather than handing back a sub-walker.

pub fn multi_point_view(self) -> Result<VariantView<'r, MultiPoint<f64>>, Error>

Return the variant payload as a VariantView.

Works on every repr. OptimisedBorrowed (the common optimised-enum case) hands back a borrowed slice with the source’s 'r lifetime — no allocation. Wire walkers re-encode (one allocation); ConvertedOwned (cross-revision convert_fn) walkers move the owned bytes.
