Expand description
EventQL parser library for parsing event sourcing query language.
This library provides a complete lexer and parser for EventQL (EQL), a query language designed for event sourcing systems. It allows you to parse EQL query strings into an abstract syntax tree (AST) that can be analyzed or executed.
Modules§
- prelude
- Convenience module that re-exports all public types and functions.
Structs§
- Access
- Field access expression (e.g.,
e.data.price). - App
- Function application (e.g.,
sum(e.price),count()). - Attrs
- Attributes attached to each expression node.
- Binary
- Binary operation (e.g.,
a + b,x == y,p AND q). - Expr
- An expression with metadata.
- Field
- A field in a record literal (e.g.,
{name: "Alice", age: 30}). - OrderBy
- ORDER BY clause specification.
- Pos
- Position information for source code locations.
- Query
- A complete EventQL query.
- Source
- A data source in a FROM clause.
- Unary
- Unary operation (e.g.,
-x,NOT active).
Enums§
- Limit
- Result set limit specification.
- Order
- Sort order direction.
- Source
Kind - The kind of data source.
- Type
- Type information for expressions.
- Value
- The kind of value an expression represents.
Functions§
- parse_
query - Parse an EventQL query string into an abstract syntax tree.
