apollo-parser@0.3.1

0.3.1 - 2022-11-04

Features

• streaming lexer - Geal + goto-bus-stop, pull/115

  To help improve performance and memory usage in the lexer, we are now
  streaming all incoming tokens in the lexer implementation.

• extend ast::*Value node conversions - SimonSapin, pull/344

  The following node types implement conversion to standard types, extracting
  their value:

  • StringValue → String
  • IntValue → i32
  • FloatValue → f64
  • BoolValue → bool

  These conversions are now also available:

  • Through the From trait, not just the Into trait
  • With borrowed nodes, not just owned

  Example:

  let node: &apollo_parser::ast::StringValue = /* something */;
  let value: String = node.clone().into(); // before
  let value = String::from(node); // now also possible

Documentation

• example of modifying queries with parser + encoder - lrlna, pull/346
  An addition to apollo-parser's example directory encoding various parts of the AST using apollo-encoder's new TryFrom implementation. Examples include:

  • merging two queries
  • omitting certain fields in a query.
