Struct EmbeddingProfileFingerprint

Namespace

MailFathom.Application.Emails.Embeddings

Assembly

MailFathom.Application.dll

Identifies one vector space by everything that decides what a vector in it means.

public readonly record struct EmbeddingProfileFingerprint : IEquatable<EmbeddingProfileFingerprint>

Implements

IEquatable<EmbeddingProfileFingerprint>

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

The profile table is unique on this value, which is what makes activation idempotent: a declaration whose geometry is already registered resolves to the existing profile instead of writing a second row that would be re-embedded from scratch for nothing. Returning to a previous model is therefore a switch rather than a duplicate. See ADR 0006.

The digest names no mail and no credential. It is computed over a deployment's own configured settings, so unlike a chunk's content hash it identifies nothing personal and needs no handling on that account.

Fields

Length

The number of characters a hexadecimal SHA-256 digest occupies.

Properties

Value

Gets the digest as sixty-four lowercase hexadecimal characters.

Methods

Compute(EmbeddingProfileIdentity)

Computes the fingerprint of one vector space.

Create(string)

Reads back a fingerprint that was written earlier.

ToString()

Returns the fully qualified type name of this instance.
