Rustly.Analyzers (v10.6.4)

Roslyn analyzers enforcing Rust-style patterns: null-safety, explicit error handling, unsafe Unwrap detection. 15 diagnostics (RUSTLY001-015).

Part of the Rustly ecosystem for .NET.

Install

dotnet add package Rustly.Analyzers --version 10.6.4

Diagnostics

ID Description Severity
RUSTLY001 Nullable return should be Option<T> Warning
RUSTLY002 Null check — use Option<T>.Match() Info
RUSTLY003 Try/catch — use Result<T, E> Info
RUSTLY004 Unsafe Unwrap()/Expect() without prior check Error
RUSTLY005 Result<T, E> return value not handled Warning
RUSTLY006 Option<T?> is redundant Warning
RUSTLY007 Use IsNone/IsOk instead of default comparison Info
RUSTLY008 Some(null) is likely a mistake Warning
RUSTLY009 Match() side-effects — use Inspect() Info
RUSTLY010 [EnumValue] missing on some members Warning
RUSTLY011 Map().UnwrapOr() — use MapOr() Info
RUSTLY012 Redundant Unwrap on known-safe value Warning
RUSTLY013 Nullable type forbidden — use Option<T> Warning¹
RUSTLY014 Null assignment forbidden — use Option<T>.None Warning
RUSTLY015 Discard suppression forbidden (_ = field;) Warning

¹ RUSTLY013 is enabled by default at Warning. To make every ? a hard error, set the rustly_only_optionen flag in your .editorconfig:

[*.cs]
rustly_only_optionen = true

When the flag is true, every T? annotation outside Option<T?> (already covered by RUSTLY006) is reported as an Error. You can alternatively configure severity directly with dotnet_diagnostic.RUSTLY013.severity = error.
