Module env_helpers 

Shared environment variable and serde-default helpers.

Consolidates the read_env_var + test-override pattern and the trivial default_true / default_enabled serde default functions that were previously duplicated across the crate.

Functions

default_enabled

Serde default returning true. Alias of default_true for use with #[serde(default = "default_enabled")].

default_true

Serde default returning true. Use with #[serde(default = "default_true")].

parse_env_bool

Parse a boolean environment variable, returning default when unset or unrecognized. Accepted truthy values: 1, true, yes, on. Accepted falsy values: 0, false, no, off. Matching is case-insensitive after trimming whitespace.

read_env_var

Read an environment variable, honoring the test-only override map.
