Summary

Duplicate adding or pasting a value to a collection

Identifiers

Field	Value
Rule code	BSL181
Compatible alias	DuplicatedInsertionIntoCollection
Severity	WARNING
Without configuration	Yes
BSLLS JSON, ON mode without overrides	Yes
Registry flag implemented	Yes

The implemented flag describes the registry; it does not certify verified BSLLS parity.

Behavior

• The public identifier BSL181 and alias DuplicatedInsertionIntoCollection are stable.
• The rule reports the cases documented on this page.
• Suppressions and project configuration are applied before publication.
• The rule requires neither an external analyzer nor network access.

Configuration and suppression

BSL### is the primary stable identifier. The compatible alias is accepted in select, ignore, and compatible block suppression comments.

[tool.onec-hbk-bsl]
select = ["BSL181"]
ignore = ["DuplicatedInsertionIntoCollection"]

All three suppression families support both a current line and a range. When an opening comment follows code, it affects only that line. Use any one form:

• noqa:

Value = "example";  // noqa: BSL181

• bsl-disable:

Value = "example";  // bsl-disable: BSL181

• compatible BSLLS form:

Value = "example";  // BSLLS:DuplicatedInsertionIntoCollection-off

When the same opening comment is on a line by itself, it starts a range. Close it with the matching marker from the same family:

// noqa: BSL181
// code without this diagnostic
// noqa-enable: BSL181

// bsl-disable: BSL181
// code without this diagnostic
// bsl-enable: BSL181

// BSLLS:DuplicatedInsertionIntoCollection-off
// code without this diagnostic
// BSLLS:DuplicatedInsertionIntoCollection-on

To disable the rule until the end of the file, omit the closing noqa-enable, bsl-enable, or BSLLS:…-on marker.

Opening and closing markers must belong to the same family.
