Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.source_type: Option<String>Specifies how retrieved data is specified. Valid values: "table", "query".
connection: Option<Option>Specifies a Glue Data Catalog Connection to a Snowflake endpoint.
schema: Option<String>Specifies a Snowflake database schema for your node to use.
table: Option<String>Specifies a Snowflake table for your node to use.
database: Option<String>Specifies a Snowflake database for your node to use.
temp_dir: Option<String>Not currently used.
iam_role: Option<Option>Not currently used.
additional_options: Option<HashMap<String, String>>Specifies additional options passed to the Snowflake connector. If options are specified elsewhere in this node, this will take precedence.
sample_query: Option<String>A SQL string used to retrieve data with the query sourcetype.
pre_action: Option<String>A SQL string run before the Snowflake connector performs its standard actions.
post_action: Option<String>A SQL string run after the Snowflake connector performs its standard actions.
action: Option<String>Specifies what action to take when writing to a table with preexisting data. Valid values: append, merge, truncate, drop.
upsert: boolUsed when Action is append. Specifies the resolution behavior when a row already exists. If true, preexisting rows will be updated. If false, those rows will be inserted.
merge_action: Option<String>Specifies a merge action. Valid values: simple, custom. If simple, merge behavior is defined by MergeWhenMatched and MergeWhenNotMatched. If custom, defined by MergeClause.
merge_when_matched: Option<String>Specifies how to resolve records that match preexisting data when merging. Valid values: update, delete.
merge_when_not_matched: Option<String>Specifies how to process records that do not match preexisting data when merging. Valid values: insert, none.
merge_clause: Option<String>A SQL statement that specifies a custom merge behavior.
staging_table: Option<String>The name of a staging table used when performing merge or upsert append actions. Data is written to this table, then moved to table by a generated postaction.
selected_columns: Option<Vec<Option>>Specifies the columns combined to identify a record when detecting matches for merges and upserts. A list of structures with value, label and description keys. Each structure describes a column.
auto_pushdown: boolSpecifies whether automatic query pushdown is enabled. If pushdown is enabled, then when a query is run on Spark, if part of the query can be "pushed down" to the Snowflake server, it is pushed down. This improves performance of some queries.
table_schema: Option<Vec<Option>>Manually defines the target schema for the node. A list of structures with value , label and description keys. Each structure defines a column.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

painted.on_red();Source§fn on_primary(&self) -> Painted<&T>

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
