Parser¶

The current parser used in Pris is a hand-written parser. See src/parser.rs for more information.

Previously, a parser generated by lalrpop was used. This parser was replaced mainly because of the long compile times caused by lalrpop and its many dependencies. The opportunity for better error messages and reduced binary size are other advantages.

Build time¶

Build times on Rust 1.19.0-beta.1, median and standard deviation of 3 clean builds, excluding crate download time:

b504558 is the lalrpop-based revision, 4bb1e60 uses the new parser.

Binary size¶

The binary size for a release build, after stripping:

That is almost a 20% reduction in binary size.
