Enum Value 

pub enum Value {
    Str(String, Span),
    Num(String, Span),
    Bool(bool, Span),
    Ident(String, Span),
    Env(String, Span),
    Func {
        name: String,
        args: Vec<Value>,
        span: Span,
    },
    Array(Vec<Value>, Span),
}

A value written in an attribute argument or a config entry.

Variants

Str(String, Span)

"text"

Num(String, Span)

A number, kept as written so integer and float stay distinguishable.

Bool(bool, Span)

true / false

Ident(String, Span)

A bare identifier, e.g. USER or Cascade.

Env(String, Span)

env("DATABASE_URL")

Func

uuid7(), dbgenerated("...")

Fields

name: String

Function name.

args: Vec<Value>

Arguments, in source order.

span: Span

Source location of the call.

Array(Vec<Value>, Span)

[a, b]
