Crate claude_quota 

claude_quota — Anthropic API quota HTTP transports.

Provides rate-limit header types and OAuth usage endpoint types as library types (always available), with network functions gated behind the enabled feature.

Testability

parse_headers accepts Fn(&str) -> Option<String> so unit tests pass a HashMap-backed closure — no live network, no ureq in dev-dependencies. parse_oauth_usage operates on a raw &str body for the same reason.

Structs

ClaudeCliRolesData

Org identity snapshot parsed from GET /api/oauth/claude_cli/roles.

MembershipRaw

One membership entry parsed from GET /api/oauth/account.

OauthAccountData

Account identity and subscription state parsed from GET /api/oauth/account.

OauthUsageData

Response from GET /api/oauth/usage — three period buckets.

PeriodUsage

Per-period quota bucket from the OAuth usage endpoint.

RateLimitData

Rate-limit utilization data parsed from Anthropic API response headers.

Enums

QuotaError

Errors produced by the quota HTTP transport.

Constants

ANTHROPIC_BETA

OAuth beta header value — must match the Claude binary’s OAuth implementation.

ANTHROPIC_VERSION

Anthropic API version header value.

API_URL

Anthropic messages endpoint used for quota checks.

CLAUDE_CLI_ROLES_URL

Claude CLI roles URL — GET endpoint returning org and workspace identity.

OAUTH_ACCOUNT_URL
