Enum CostEstimateConfidence 

pub enum CostEstimateConfidence {
    PricedSample,
    VerifiedAllAlreadyStored,
    AllSamplesAlreadyStoredIncomplete,
}

Confidence attached to an UploadCostEstimate’s storage_cost_atto.

estimate_upload_cost prices a file by sampling a few of its chunk addresses and extrapolating. When every sampled chunk is already stored there is no live price to extrapolate from, so a "0" cost can mean either “provably free” (the whole file was sampled) or only “probably free” (the tail was unsampled). This lets callers tell those apart instead of treating every "0" as unconditionally free.

Variants

PricedSample

At least one sampled chunk returned a live quote; storage_cost_atto is extrapolated from a real per-chunk price. The normal case.

VerifiedAllAlreadyStored

Every chunk in the file was sampled and every one was already stored. storage_cost_atto is exactly "0" — the upload is genuinely free.

AllSamplesAlreadyStoredIncomplete

Every sampled chunk was already stored, but not all chunks were sampled. storage_cost_atto is "0" as a best-effort guess; the real upload reconciles the true cost at payment time. Render this as “likely already stored”, not a guaranteed-free price.

Trait Implementations

impl Clone for CostEstimateConfidence

fn clone(&self) -> CostEstimateConfidence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CostEstimateConfidence

impl Debug for CostEstimateConfidence

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

Formats the value using the given formatter.

impl Default for CostEstimateConfidence

fn default() -> CostEstimateConfidence

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CostEstimateConfidence

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CostEstimateConfidence

impl PartialEq for CostEstimateConfidence

fn eq(&self, other: &CostEstimateConfidence) -> 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 Serialize for CostEstimateConfidence

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
