🌐 Web query:

What is the latest version of lexical-parse-float crate on crates.io?

💡 Result:

The latest version is 1.0.5 (published Jan 10, 2025). [1][2]

Sources:

• Fedora crate update (lists lexical-parse-float 1.0.5). [1]
• Fedora packages page showing release 1.0.5 in Fedora Rawhide/Stable. [2]

Use the published crate version (v1.0.5)
In compiler/literal/Cargo.toml (line 16), change

lexical-parse-float = { version = "1.0.6", features = ["format"] }

to

lexical-parse-float = { version = "1.0.5", features = ["format"] }

(1.0.6 is not published on crates.io)

In compiler/literal/Cargo.toml around line 16, the dependency specifies
lexical-parse-float version "1.0.6" which is not published; change the version
to "1.0.5" while keeping the features = ["format"] entry unchanged so the crate
resolves from crates.io.

⚠️ Potential issue | 🔴 Critical

Justify the use of build_unchecked() and verify it's necessary.

The change from build() to build_unchecked() removes runtime validation of the format configuration. While this is likely safe since the format is based on the predefined PYTHON3_LITERAL with a minor modification, this needs justification.

Possible reasons for this change:

1. The build() method may no longer be const-compatible in lexical-parse-float 1.0.6
2. Performance optimization for a compile-time constant

Please verify:

• Is this change required by the updated dependency version?
• Are the safety invariants upheld (valid format configuration)?

Consider adding a comment explaining why build_unchecked() is safe here, unless this is already documented elsewhere.

🌐 Web query:

Does lexical-parse-float 1.0.6 support const build() method on NumberFormatBuilder, or does it require build_unchecked() for const contexts?

💡 Result:

You can use the const build() method — NumberFormatBuilder::build is a const fn, so you do not need build_unchecked() for const contexts. [1][2]

Sources:

• NumberFormatBuilder (const build) — lexical-core docs. [1]
• Examples showing const usage with NumberFormatBuilder::build — lexical / lexical-parse-float docs. [2]

Replace build_unchecked() with build()

File: compiler/literal/src/float.rs:21
NumberFormatBuilder::build() is a const fn and performs validation; using build_unchecked() bypasses these checks unnecessarily. Update to .build().

In compiler/literal/src/float.rs around lines 19 to 21, the NumberFormatBuilder
call uses .build_unchecked() which bypasses validation; replace that call with
.build() since NumberFormatBuilder::build() is a const fn that performs the
necessary checks. Update the chained call to call .build() instead of
.build_unchecked(), keeping the same surrounding code and ensuring the constant
assignment remains valid.
