Struct SnowflakeEngineConfig 

pub struct SnowflakeEngineConfig {

    pub default_account: Option<String>,
    pub default_user: Option<String>,
    pub default_host: Option<String>,
    pub default_warehouse: Option<String>,
    pub default_role: Option<String>,
    pub default_database: Option<String>,
    pub default_schema: Option<String>,
    pub auth: AuthMethod,
    pub pool_size: usize,
    pub http_timeout: Duration,
    pub auth_timeout: Duration,
    pub query_timeout: Duration,
    pub heartbeat_interval: Duration,
}

Engine defaults, resolved from environment variables and then ~/.omni-dev/settings.json (the Atlassian credential-resolution pattern).

Account/user/context are optional; a request supplies its own and falls back to these. There is no hardcoded account list or alias map.

Fields

default_account: Option<String>

Default account when a request omits --account.

default_user: Option<String>

Default user when a request omits --user.

default_host: Option<String>

Override the API host (verbatim) instead of deriving <account>.snowflakecomputing.com. Set for PrivateLink / gov / custom hosts; applies to every session this engine creates.

default_warehouse: Option<String>

Default warehouse applied at session creation.

default_role: Option<String>

Default role applied at session creation.

default_database: Option<String>

Default database applied at session creation.

default_schema: Option<String>

Default schema applied at session creation.

auth: AuthMethod

How sessions authenticate (SSO by default; PAT or key-pair JWT for non-interactive/headless use). The credential is the same for every session in every pool this engine creates.

pool_size: usize

Max concurrent sessions (and browser auths) per (account, user).

http_timeout: Duration

Per-request HTTP timeout for REST calls.

auth_timeout: Duration

Overall deadline for one sign-in (SSO + login) so a hung auth can’t hold the shared auth gate indefinitely.

query_timeout: Duration

Overall deadline for one query (submit + async-result polling).

heartbeat_interval: Duration

How often the background task heartbeats idle sessions to keep their master token alive. Zero disables the heartbeat.

Implementations

impl SnowflakeEngineConfig

pub fn from_env_and_settings() -> Result<Self>

Resolves defaults from env vars (then settings.json). Cheap and side-effect-free; never authenticates.

Errors

If SNOWFLAKE_AUTHENTICATOR names an unknown method or a selected non-interactive method is missing its credential (see [resolve_auth_method]).

Trait Implementations

impl Clone for SnowflakeEngineConfig

fn clone(&self) -> SnowflakeEngineConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SnowflakeEngineConfig

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

Formats the value using the given formatter.

impl Default for SnowflakeEngineConfig

fn default() -> Self

Returns the “default value” for a type.
