Updates snafu from 0.8.9 to 0.9.0

Changelog

Sourced from snafu's changelog.

[0.9.0] - 2026-03-02

Added

• WhateverLocal is an alternate to Whatever that does not implement or require Send or Sync.

• Errors that do not use context selectors (e.g. opaque errors, #[snafu(context(false))] errors, or #[snafu(transparent)] errors) may now be constructed using a generic value when they are annotated with the #[snafu(source(from(generic)))] attribute.

• When using the unstable-provider-api feature flag, Report will check if each error provides a Location. When it does, the Location will be appended to the error message.

Fixed

• Opaque errors which use const generics with default values are now supported.

Changed

• Rust 1.65 is now the minimum supported Rust version. This is a breaking change.

• Rust 1.81 is now the default supported Rust version. This is a breaking change.

• Whatever implements Send and Sync, allowing it to be sent between threads. This requires that wrapped errors also implement Send and Sync. This is a breaking change.

• snafu::Location has been replaced with a type alias to the standard library's Location (specifically a reference to that type: &'static core::panic::Location<'static>). This improves interoperability and access to features. This is a breaking change.

• Opaque errors default to allowing construction from any value that implements Into for the wrapped type. The previous behavior can be restored with #[snafu(source(from(exact)))]. This is a breaking change.

• The internal implementation of #[snafu] attribute parsing has been rewritten. This should largely be unnoticeable, but some error messages and spans have been improved, and memory usage may be slightly reduced.

[lance-gatekeeper]

✅ Gate recommendation: approve.

The anyhow update includes the upstream fix for Error::downcast_mut, and snafu now shares Lance's existing 0.9 package, removing the duplicate 0.8 crates. The locked Rust check passes on this rebased revision.
