Struct ResolvedConfig 

pub struct ResolvedConfig {
    pub store_root: Utf8PathBuf,
    pub log_dir: Utf8PathBuf,
    pub log_path: Utf8PathBuf,
    pub config_dir: Utf8PathBuf,
    pub config_path: Utf8PathBuf,
    pub contact_email: Option<String>,
    pub unpaywall_email: Option<String>,
}

Snapshot of the env-var + default-fallback config that doiget would use on the current machine.

Phase 1 surface: env vars only (DOIGET_STORE_ROOT, DOIGET_LOG_PATH, DOIGET_CONTACT_EMAIL, DOIGET_UNPAYWALL_EMAIL) layered over XDG / known-folder defaults. Phase 2 will layer the user config.toml underneath the env vars per docs/CONFIG.md §1.

Issue #142: log_path is resolved from DOIGET_LOG_PATH — the ONLY log env var docs/CONFIG.md §4 documents — using the exact same resolution the provenance-log writer (commands::fetch::resolve_log_path / commands::audit_log) uses, so config show reports the path the writer actually uses. The previously read, undocumented DOIGET_LOG_DIR has been dropped.

Fields

store_root: Utf8PathBuf

Root of the on-disk paper store. Default: $HOME/papers.

log_dir: Utf8PathBuf

Directory holding doiget’s append-only logs. Derived from log_path’s parent so it always agrees with the writer.

log_path: Utf8PathBuf

JSON-Lines provenance log file path. DOIGET_LOG_PATH when set, otherwise <config_dir>/doiget/access.jsonl (docs/CONFIG.md §4).

config_dir: Utf8PathBuf

Directory holding config.toml and credentials.toml.

config_path: Utf8PathBuf

Path of the user config file (may not exist on disk yet).

contact_email: Option<String>

Contact email for the polite User-Agent header (and Unpaywall fallback).

unpaywall_email: Option<String>

Unpaywall-specific contact email; falls back to contact_email when unset.

Implementations

impl ResolvedConfig

pub fn from_env() -> Result<Self>

Resolve the live config from process environment + platform defaults.

Errors only if neither a home directory nor a config directory can be determined for the current user (e.g. an unknown / locked-down platform); on every realistic POSIX or Windows host this returns Ok even with no DOIGET_* env vars set.

Trait Implementations

impl Debug for ResolvedConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Serialize for ResolvedConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
