What differs at a Difference’s location.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Malformed

A program could not be materialized into canonical form, so the comparison is undefined for it.

Fields

program: ProgramSide

Which program failed to materialize.

message: String

The materialization error’s message.

Settings

The programs’ settings differ.

DeclarationTable

A declaration table declares a different index set.

Fields

table: DeclarationTable

The declaration table that differs.

first: Vec<u32>

The sorted indices the first program declares.

second: Vec<u32>

The sorted indices the second program declares.

Count

Compared element counts differ; element names the compared list — "rules", "subroutine rules", "conditions", "actions", "branches", "arguments", or "elements".

Fields

element: &'static str

The compared list.

first: usize

The count in the first program.

second: usize

The count in the second program.

Event

The compared rules’ events differ; first and second describe the two events.

Fields

first: String

second: String

Shape

The compared nodes have different kinds, e.g. "setGlobalVariable" vs "modifyGlobalVariable" or "number" vs "call".

Fields

first: &'static str

The first program’s node kind.

second: &'static str

The second program’s node kind.

Reference

Variable or subroutine references resolve to different declaration indices.

Fields

table: DeclarationTable

The declaration table the reference resolves through.

first: u32

The index the first program’s reference resolves to.

second: u32

The index the second program’s reference resolves to.

Operation

Modify operations differ ("add", "subtract", …).

Fields

first: String

second: String

Scalar

Scalar payloads differ — numbers, strings, enum members, call ids.

Fields

first: String

second: String
