Struct ServerDigest 

pub struct ServerDigest {
    pub algorithm: String,
    pub rows: u64,
    pub digest: String,
    pub key_min: Option<i64>,
    pub key_max: Option<i64>,
}

A digest a backend computed itself, without shipping rows. Two server digests are comparable only when their algorithm ids match — each backend hashes its own text rendering of a row, so a Postgres digest says nothing about a SQLite table. When the algorithms differ the verifier streams both sides and uses ContentDigest instead.

Fields

algorithm: String

rows: u64

digest: String

Opaque digest text (a decimal sum, a hex string — whatever the algorithm defines).

key_min: Option<i64>

key_max: Option<i64>

Implementations

impl ServerDigest

pub fn comparable(&self, other: &ServerDigest) -> bool

Whether two server digests agree. Different algorithms never agree — the caller must not treat that as a difference but as “not comparable”.

pub fn same(&self, other: &ServerDigest) -> bool

pub fn bounds_union(&self, other: &ServerDigest) -> Option<(i64, i64)>
