Enum ConfigValue 

pub enum ConfigValue {
    Inline(String),
    Env(String),
}

A config value that is either inline or an env-var reference.

In TOML this deserializes from "literal" or { env = "VAR_NAME" } — the same shape drizzle-kit and the CLI accept for dbCredentials.url. Used anywhere a config value can be either inline or pulled from the environment at runtime.

Variants

Inline(String)

Value written inline in the config file.

Env(String)

Name of the environment variable to resolve.

Implementations

impl ConfigValue

pub fn resolve(&self) -> Result<String, ConfigValueError>

Resolve to a concrete string, reading the environment if needed.

Errors

Returns ConfigValueError::NotPresent if this is a ConfigValue::Env pointing to a variable that is not set, or ConfigValueError::NotUnicode if the variable is set but contains invalid UTF-8.

pub fn resolve_optional(&self) -> Result<Option<String>, ConfigValueError>

Resolve to an optional value (returns None when an Env var is unset).

Errors

Returns ConfigValueError::NotUnicode if the env var is set but contains invalid UTF-8. Missing env vars resolve to Ok(None).
