Struct License 

Source 
pub struct License {
    pub sub: String,
    pub iss: Issuer,
    pub tier: Tier,
    pub rwu_limit: Option<NonZeroU64>,
    pub exp: u64,
}
Expand description

The content of a license.

We use JSON Web Token (JWT) to represent the license. This struct is the payload.

Prefer calling crate::Feature::check_available to check the availability of a feature, other than directly checking the content of the license.

Fields§

§sub: String

Subject of the license.

See https://tools.ietf.org/html/rfc7519#section-4.1.2.

§iss: Issuer

Issuer of the license.

See https://tools.ietf.org/html/rfc7519#section-4.1.1.

§tier: Tier

Tier of the license.

§rwu_limit: Option<NonZeroU64>

Maximum number of RWU allowed to use.

1 RWU corresponds to 4 GiB memory and 1 CPU core. See https://docs.risingwave.com/cloud/pricing#risingwave-unit-rwu for more details.

§exp: u64

Expiration time in seconds since UNIX epoch.

See https://tools.ietf.org/html/rfc7519#section-4.1.4.
