[dependabot]

Bumps regex from 1.9.0 to 1.9.3.

Changelog

Sourced from regex's changelog.

1.9.3 (2023-08-05)

This is a patch release that fixes a bug where some searches could result in incorrect match offsets being reported. It is difficult to characterize the types of regexes susceptible to this bug. They generally involve patterns that contain no prefix or suffix literals, but have an inner literal along with a regex prefix that can conditionally match.

Bug fixes:

• [BUG #1060](rust-lang/regex#1060): Fix a bug with the reverse inner literal optimization reporting incorrect match offsets.

1.9.2 (2023-08-05)

This is a patch release that fixes another memory usage regression. This particular regression occurred only when using a RegexSet. In some cases, much more heap memory (by one or two orders of magnitude) was allocated than in versions prior to 1.9.0.

Bug fixes:

• [BUG #1059](rust-lang/regex#1059): Fix a memory usage regression when using a RegexSet.

1.9.1 (2023-07-07)

This is a patch release which fixes a memory usage regression. In the regex 1.9 release, one of the internal engines used a more aggressive allocation strategy than what was done previously. This patch release reverts to the prior on-demand strategy.

Bug fixes:

• [BUG #1027](rust-lang/regex#1027): Change the allocation strategy for the backtracker to be less aggressive.
