Struct OperationWalker 

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

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

Implementations

impl<'r, R: BorrowedReader + 'r> OperationWalker<'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_add(&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 add_view(self) -> Result<VariantView<'r, ()>, Error>

Return the variant payload bytes as a VariantView.

Multi-field tuple and struct variants have no single inner type, so into_<variant> is not available; this _view hands you the body bytes and you can decode the variant’s fields sequentially (or feed the bytes into another walker).

pub fn is_remove(&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 remove_view(self) -> Result<VariantView<'r, ()>, Error>

Return the variant payload bytes as a VariantView.

Multi-field tuple and struct variants have no single inner type, so into_<variant> is not available; this _view hands you the body bytes and you can decode the variant’s fields sequentially (or feed the bytes into another walker).

pub fn is_replace(&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 replace_view(self) -> Result<VariantView<'r, ()>, Error>

Return the variant payload bytes as a VariantView.

Multi-field tuple and struct variants have no single inner type, so into_<variant> is not available; this _view hands you the body bytes and you can decode the variant’s fields sequentially (or feed the bytes into another walker).

pub fn is_change(&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 change_view(self) -> Result<VariantView<'r, ()>, Error>

Return the variant payload bytes as a VariantView.

Multi-field tuple and struct variants have no single inner type, so into_<variant> is not available; this _view hands you the body bytes and you can decode the variant’s fields sequentially (or feed the bytes into another walker).

pub fn is_copy(&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 copy_view(self) -> Result<VariantView<'r, ()>, Error>

Return the variant payload bytes as a VariantView.

Multi-field tuple and struct variants have no single inner type, so into_<variant> is not available; this _view hands you the body bytes and you can decode the variant’s fields sequentially (or feed the bytes into another walker).

pub fn is_move(&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 move_view(self) -> Result<VariantView<'r, ()>, Error>

Return the variant payload bytes as a VariantView.

Multi-field tuple and struct variants have no single inner type, so into_<variant> is not available; this _view hands you the body bytes and you can decode the variant’s fields sequentially (or feed the bytes into another walker).

pub fn is_test(&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 test_view(self) -> Result<VariantView<'r, ()>, Error>

Return the variant payload bytes as a VariantView.

Multi-field tuple and struct variants have no single inner type, so into_<variant> is not available; this _view hands you the body bytes and you can decode the variant’s fields sequentially (or feed the bytes into another walker).
