Implementations

impl Value

pub fn is_null(&self) -> bool

pub fn to_sql_text(&self) -> Option<String>

How this value is written into SQL text for the wire.

Parameters are sent out of band (never interpolated into the statement), so this is only the textual encoding of a bound parameter.

pub fn to_display(&self) -> String

Render for a human: log lines, Telescope, error messages.
