Crate cyrs 

cypher — meta-crate re-exporting the full front-end library surface.

Consumers that want “everything for parsing Cypher and turning it into a typed plan” depend on this crate. Consumers with tighter needs (parse-only, schema-only, etc.) depend on the specific member crate.

Feature flags (spec 0001 §17.15):

• default — full library surface: core + fmt + schema
• lsp-only — library deps consumed by the LSP binary (core + fmt)
• fmt-only — formatter slice (core + fmt)
• schema-only — schema / type-system slice (core + schema)
• no-default-features — empty; downstream picks slices explicitly

Note: cyrs-lsp is a pure binary crate (no lib target), so it is not re-exported here. Use cargo check -p cyrs-lsp to verify the LSP binary compiles.

Spec 0001 §3.1.

Structs

CypherDatabase

The concrete incremental database (Salsa 2022-style, spec §11.1).

Database

Workspace-scoped incremental analysis database (spec §11).

Diagnostic

A single diagnostic. Spec §10.1.

EmptySchema

A SchemaProvider that reports nothing. Useful for schema-free mode and for unit tests that do not want to construct a full schema.

FileId

A stable, workspace-scoped file identity (spec §11.4).

Parse

A completed parse: green tree + accumulated syntax errors.

ParseOutput

Memoised result of parsing a SourceFile.

SourceFile

A single source file tracked by the incremental database.

Enums

DiagCode

Stable diagnostic code. Rendered as E0001 / W6001 / N8001.

DialectMode

Dialect mode selected at parse time. Spec §9.

Severity

Diagnostic severity (spec §10.3). Error failures set exit code 1 in cypher check; the others are informational.

SyntaxKind

Every syntactic category in Cypher: tokens, nodes, and meta.

Traits

CypherDb

Trait that all concrete databases in this workspace implement.

SchemaProvider

The single trait consumers implement to feed schema into the front-end.

Functions

parse

Entry point. Parses a complete source file.
