Enum AiBackend 

pub enum AiBackend {
    Default,
    ClaudeCli,
    OpenAi,
    Ollama,
    Bedrock,
}

The AI backend used by commands that invoke an AI model.

One enum serves both the --ai-backend CLI flag (via clap::ValueEnum) and the resolved dispatch in the client factory and preflight (STYLE-0019). Selection precedence is documented on resolve_backend.

Variants

Default

Direct HTTP to the Anthropic API. Selecting this explicitly overrides the legacy USE_* env vars.

ClaudeCli

Shell out to the claude -p CLI (reuses an existing Claude Code auth session). Equivalent to setting OMNI_DEV_AI_BACKEND=claude-cli.

OpenAi

OpenAI API. Equivalent to setting OMNI_DEV_AI_BACKEND=openai (legacy selector: USE_OPENAI=true).

Ollama

Local Ollama (or another OpenAI-compatible local server). Equivalent to setting OMNI_DEV_AI_BACKEND=ollama (legacy: USE_OLLAMA=true).

Bedrock

AWS Bedrock with Claude models. Equivalent to setting OMNI_DEV_AI_BACKEND=bedrock (legacy: CLAUDE_CODE_USE_BEDROCK=true).

Implementations

impl AiBackend

pub fn env_value(self) -> &'static str

Returns the canonical AI_BACKEND_ENV value for this backend.

pub fn from_env_value(value: &str) -> Option<Self>

Parses an AI_BACKEND_ENV value.

Accepts the canonical kebab-case values plus the legacy claude_cli underscore alias. Returns None for anything else.

Trait Implementations

impl Clone for AiBackend

fn clone(&self) -> AiBackend

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for AiBackend

impl Debug for AiBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for AiBackend

impl PartialEq for AiBackend

fn eq(&self, other: &AiBackend) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for AiBackend

impl ValueEnum for AiBackend

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
