Enum CatalogLine 

pub enum CatalogLine {
    VcpuSecond,
    MemoryGbSecond,
    SnapshotStorageGbHour,
    SnapshotReadGb,
    SnapshotWriteGb,
}

One rate the catalog has to carry, and what it fills.

The Python held this as pricing.MICROVM_LINES, a tuple of RateLine records naming a group, a usagetype, a unit, and — for the two compute lines — an x86_group probed only when the ARM line was missing. Same shape here, as a closed enum: the catalog has five lines this client reads, and a sixth is not a value that exists.

Variants

VcpuSecond

MemoryGbSecond

SnapshotStorageGbHour

Quoted per GB-hour by the API. Converted once, in RateTable::from_catalog.

SnapshotReadGb

SnapshotWriteGb

Implementations

impl CatalogLine

pub const ALL: [CatalogLine; 5]

Every line, in the order the Python’s MICROVM_LINES declares them.

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

The region-independent group attribute, which is what a fetch filters on.

usagetype carries a location prefix in every region except us-east-1 (Lambda-MicroVM-vCPU-Second-ARM is USW2-Lambda-MicroVM-vCPU-Second-ARM in us-west-2), so comparing raw usage types across regions matches nothing and yields a table of holes rather than an error. group does not.

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

The RateTable field this fills, as the Python’s RateLine.field spells it — so a drift report names the same thing in both clients.

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

The unit the API must report for this line.

Checked rather than assumed. It is the only signal available if AWS restates storage per GB-month: the number would change by 730x and every arithmetic check downstream would still pass, because they all read the same table.

pub fn x86_group(self) -> Option<&'static str>

The x86 sibling, for the two compute lines that have one (COST-9).

Named so the refusal can say what it is refusing. MicroVMs are ARM64-only — the Architecture shape is enum: ['ARM_64'] with no other member — so the x86 rate can never apply, and it is 17.9% higher. Snapshot lines have no architecture variant, so there is nothing to refuse.

pub fn is_per_hour(self) -> bool

True for storage, quoted per GB-hour where RateTable holds per GB-month.
