Struct CollectionInfo 

pub struct CollectionInfo {
    pub name: String,
    pub dimension: usize,
    pub metric: String,
    pub vector_count: usize,
    pub document_count: usize,
    pub created_at: String,
    pub updated_at: String,
    pub indexing_status: Option<IndexingStatus>,
    pub size: Option<Value>,
    pub quantization: Option<Value>,
    pub normalization: Option<Value>,
    pub status: Option<String>,
}

Collection information.

The v3.0.0 REST surface returns metric in Rust-Debug form (e.g. "Cosine"), plus new top-level blocks (size, quantization, normalization, status). Every field beyond name + dimension carries #[serde(default)] so the model tolerates pre-v3 servers and future additions (request models keep the strict posture; this is a response-only struct).

Fields

name: String

Collection name

dimension: usize

Vector dimension

metric: String

Similarity metric used for search. The v3 server emits this in Rust-Debug form ("Cosine" / "Euclidean" / "DotProduct"); callers that compare against "cosine" etc. should go through .to_lowercase().

vector_count: usize

Number of vectors in the collection

document_count: usize

Number of documents in the collection

created_at: String

Creation timestamp (RFC3339). Optional — pre-v3 servers may omit.

updated_at: String

Last update timestamp (RFC3339). Optional — pre-v3 servers may omit.

indexing_status: Option<IndexingStatus>

Indexing status. Absent on the v3 server; some legacy servers send it.

size: Option<Value>

Size block emitted by v3 ({total, total_bytes, index, index_bytes, payload, payload_bytes}).

quantization: Option<Value>

Quantization block emitted by v3 ({enabled, type, bits}).

normalization: Option<Value>

Normalization block emitted by v3.

status: Option<String>

Ready/indexing/error state emitted by v3.
