Struct ValueFormatter

pub struct ValueFormatter;

Expand description

ValueFormatter provides cqlsh-compatible string formatting for CQL values

Implementations§

impl ValueFormatter

pub fn format_value(value: &Value) -> String

Format a Value to its string representation according to the contract specification

§Contract Guarantees

UUID/TimeUUID: lowercase hyphenated (e.g., “a8f167f0-ebe7-4f20-a386-31ff138bec3b”)
Timestamps: YYYY-MM-DD HH:MM:SS[.fff][+0000], default UTC
Collections: list [a, b], set {a, b}, map {k: v}
Blob: 0x-prefixed lowercase hex
Boolean: true/false
Numbers: standard Rust formatting, avoid scientific notation unless necessary
