Enum Limit 

#[non_exhaustive]
pub enum Limit {
    Aws,
    Azure,
    Gcp,
}

How large a provider lets a machine’s user data be, in bytes of the document it receives (design §4.9 cloud design; a docker-vm, Proxmox or ESXi snippet has no such cap).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Aws

AWS: 16 KiB of raw user data.

Azure

Azure: 64 KiB.

Gcp

Google Cloud: 256 KiB.

Implementations

impl Limit

pub fn bytes(self) -> usize

The cap in bytes.

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

The provider’s name, for a refusal.

pub fn fits(self, user_data: &str) -> Result<(), TooBig>

Ok when user_data (the document the provider receives) fits; otherwise TooBig, which a caller turns into a refusal naming the machine.

Errors

TooBig when the document is over the cap, with its size and the overflow.
